F A N 2500 — 100 m A C M O S L D O R eg u lato r © 2010 Fairchild Semiconductor Corporation www.fairchildsemi.com FAN2500 Rev. 1.1.0 9 Functional Description Designed utilizing CMOS process technology, the FAN2500 is carefully optimized for use in compact bat- tery-powered devices. The FAN2500 offers a unique combination of low power consumption, extremely low dropout voltages, high tolerance for a variety of output capacitors, and the ability to disable the output to less than 1 μA under user control. In the circuit, a difference amplifier controls the current through a series-pass P- channel MOSFET, comparing the load voltage at the out- put with an onboard low-drift band-gap reference. The series resistance of the pass P-channel MOSFET is approximately 1 Ω, resulting in an unusually low dropout voltage under load compared to older bipolar pass-tran- sistor designs. Protection circuitry is provided onboard for overload con- ditions. If the device reaches temperatures exceeding the specified maximums, an onboard circuit shuts down the output and it remains suspended until it has cooled before re-enabling. The user can shut down the device using the Enable control pin at any time. Careful design of the output regulator amplifier assures loop stability over a wide range of ESR values in the external output capacitor. A wide range of values and types can be accommodated, allowing the user to select a capacitor meeting space, cost, and performance requirements; and still enjoy reliable operation over tem- perature, load, and tolerance variations. Depending on the model selected, a number of control and status functions are available to enhance the opera- tion of the LDO regulator. An Enable pin, available on all devices, allows the user to shut down the regulator out- put to conserve power, reducing supply current to less than 1 μA. The adjustable-voltage versions of the device utilize pin 4 to connect to an external voltage divider that feeds back to the regulator error amplifier, thereby set- ting the voltage as desired. Two other functions are avail- able at pin 4 in the fixed-voltage versions: in noise- sensitive applications, an external bypass capacitor con- nection is provided that allows the user to achieve opti- mal noise performance at the output, while the error output functions as a diagnostic flag to indicate that the output voltage has dropped more than 5% below the nominal fixed voltage. Applications Information External Capacitors – Selection FAN2500 supports a wide variety of capacitors com- pared to other LDO products. An innovative design approach offers significantly reduced sensitivity to ESR (Equivalent Series Resistance), which degrades regula- tor loop stability in older designs. While the improve- ments greatly simplify the design task, capacitor quality still must be considered to achieve optimal circuit perfor- mance. In general, ceramic capacitors offer superior ESR perfor- mance at a lower cost and a smaller case size than tan- talum. Those with X7R or Y5V dielectric offer the best temperature coefficient characteristics. The combination of tolerance and variation over temperature in some capacitor types can result in significant variations, result- ing in unstable performance over rated conditions. Input Capacitor An input capacitor of 2.2 μF (nominal value) or greater, connected between the Input pin and ground, located in close proximity to the device, improves transient response and noise rejection. Higher values offer supe- rior input ripple rejection and transient response. An input capacitor is recommended when the input source, either a battery or a regulated AC voltage, is located far from the device. Any good-quality ceramic, tantalum, or metal film capacitor gives acceptable performance; how- ever, tantalum capacitors with a surge current rating appropriate to the application must be selected to avoid catastrophic failure. Output Capacitor An output capacitor is required to maintain regulator loop stability. Unlike many other LDO regulators, the FAN2500 is nearly insensitive to output capacitor ESR. Stable operation is achieved with a wide variety of capacitors with ESR values ranging from 10 mΩ to 10 Ω or more. Tantalum, aluminum electrolytic, or multilayer ceramic can be used. A nominal value of at least 1 μF is recommended. Bypass Capacitor (FAN2500 Only) In the fixed-voltage configuration, connecting a capacitor between the Bypass pin and ground can significantly reduce noise on the output. Values ranging from 470 pF to 10 nF can be used, depending on the sensitivity to output noise in the application. At the high-impedance Bypass pin, care must be taken in the circuit layout to minimize noise pickup and capacitors must be selected to minimize current loading (leakage). Noise pickup from external sources can be considerable. Leakage currents into the Bypass pin directly affect regu- lator accuracy and should be kept as low as possible; high-quality ceramic and film types are recommended for their low leakage characteristics. Cost-sensitive applica- tions not concerned with noise can omit this capacitor. Control Functions Enable Pin Applying a voltage of 0.4 V or less at the Enable pin dis- ables the output, reducing the quiescent output current to less than 1 μA; while a voltage of 2.0 V or greater enables the device. If this shutdown function is not needed, the pin can be connected to the VIN pin. Allow- ing this pin to float causes erratic operation.

F A N 2500 — 100 m A C M O S L D O R eg u lato r © 2010 Fairchild Semiconductor Corporation www.fairchildsemi.com FAN2500 Rev. 1.1.0 10 Thermal Protection FAN2500 can supply high peak output currents of up to 1 A for brief periods. However, this output load causes the device temperature to exceed maximum ratings due to power dissipation. During output overload conditions, when the die temperature exceeds the shutdown limit temperature of 150°C, onboard thermal protection dis- ables the output until the temperature drops below this limit, at which point the output is re-enabled. During a thermal shutdown situation, the user may assert the power-down function at the Enable pin, reducing power consumption to the minimum level IGND· VIN. Thermal Characteristics FAN2500 can supply 100 mA at the specified output volt- age with an operating die (junction) temperature of up to 125°C. Once the power dissipation and thermal resis- tance is known, the maximum junction temperature of the device can be calculated. While the power dissipa- tion is calculated from known electrical parameters, the thermal resistance is a result of the thermal characteris- tics of the compact SOT23-5 surface-mount package and the surrounding PC board copper to which it is mounted. The power dissipation is equal to the product of the input to output voltage differential and the output current, plus the ground current multiplied by the input voltage, or: The ground pin current, IGND, can be found in the charts provided in the Electrical Characteristics section. The relationship describing the thermal behavior of the package is: where TJ(max) is the maximum allowable junction temper- ature of the die, which is 125°C, and TA is the ambient operating temperature. θJA is dependent on the sur- rounding PC board layout and can be empirically obtained. While the θJC (junction-to-case) of the SOT23- 5 package is specified at 130°C /W, the θJA of the mini- mum PWB footprint is at least 235°C/W. This can be improved by providing a heat sink of surrounding copper ground on the PCB. Depending on the size of the copper area, the resulting θJA can range from approximately 180°C/W for one square inch to nearly 130°C/W for four square inches. The addition of backside copper with through-holes, stiff- eners, and other enhancements can reduce this value. The heat contributed by the dissipation of other devices nearby must be included in design considerations. PD VIN VOUT–( )IOUT VINIGND+= PD max( ) TJ max( ) TA– θJA ------------------------------- ⎩ ⎭ ⎨ ⎬ ⎧ ⎫ = Once the limiting parameters in these two relationships have been determined, the design can be modified to ensure that the device remains within specified operating conditions at all times. If overload conditions are not considered, it is possible for the device to enter a thermal cycling loop, in which the circuit enters a shutdown condition, cools, re- enables, and then again overheats and shuts down repeatedly due to an unmanaged fault condition. Operational of Adjustable Version The adjustable version of the FAN2500 includes an input pin, ADJ, which allows the user to select an output volt- age ranging from 1.8 V to near VIN, using an external resistor divider. The voltage VADJ presented to the ADJ pin is fed to the onboard error amplifier, which adjusts the output voltage until VADJ is equal to the onboard bandgap reference voltage of 1.32 V (typ). The equation is: The total value of the resistor chain should not exceed 250 kΩ total to keep the error amplifier biased during no- load conditions. Programming output voltages very near VIN need to allow for the magnitude and variation of the dropout voltage VDO over load, supply, and temperature variations. Note that the low-leakage MOSFET input to the CMOS error amplifier induces no bias current error to the calculation. General PCB Layout Considerations To achieve the full performance of the device, careful cir- cuit layout and grounding technique must be observed. Establishing a small local ground, to which the GND pin, the output, and bypass capacitors are connected; is rec- ommended. The input capacitor should be grounded to the main ground plane. The quiet local ground is routed back to the main ground plane using feed-through vias. In general, the high-frequency compensation compo- nents (input, bypass, and output capacitors) should be located as close to the device as possible. The proxim- ity of the output capacitor is especially important to achieve optimal noise compensation from the onboard error amplifier, especially during high load conditions. A large copper area in the local ground provides the heat sinking discussed above when high power dissipation significantly increases the temperature of the device. Component-side copper provides significantly better thermal performance for this surface-mount device, com- pared to that obtained when using only copper planes on the underside.
