AS1361/AS1362 150mA/300mA, Ultra-Low-Noise, High-PSRR Low Dropout Regulators, with POK Datasheet1 General Description The AS1361/AS1362 are ultra-low-noise, low-dropout linear regulators specifically designed to deliver up to 150/300mA continuous output current, and can achieve a low 140mV dropout for 300mA load current. The LDOs are designed and optimized to work with low-cost, small- capacitance ceramic capacitors. The devices are available as the standard products listed in Table 1. An integrated P-channel MOSFET pass transistor allows the devices to maintain extremely low quiescent current (40µA). The AS1361/AS1362 uses an advanced architecture to achieve ultra-low output voltage noise of 9µVRMS and a power-supply rejection-ratio of better than 80dB (up to 10kHz). An active-Low, open-drain power-ok output indicates if the output voltage is within regulation. The AS1361/AS1362 requires only 1µF output capacitor for stability at any load. When the LDO is disabled, cur- rent consumption drops below 500nA. The devices are available in a TSOT23 6-pin package. Figure 1. Typical Application Circuit 2 Key Features !

AS1361/AS1362 Datasheet - Deta i led Descr ip t ion8 Detailed Description The AS1361/AS1362 are ultra-low-noise, low-dropout, low-quiescent current linear-regulators specifically designed for space-limited applications. The devices are available with preset output voltages from 1.5 to 4.5V in 50mV increments. These devices can supply loads up to 150/300mA. As shown in Figure 18, the AS1361/AS1362 consist of an inte- grated bandgap core and noise bypass circuitry, error amplifier, P-channel MOSFET pass transistor, and internal feed- back voltage-divider. The output voltage is fed back through an internal resistor voltage-divider connected to pin OUT. An external bypass capacitor connected to pin BYPASS reduces noise at the output. Additional blocks include a current limiter, thermal sensor, and shutdown logic. Internal Voltage Reference The 1.25V bandgap reference is connected to the error amplifier’s inverting input. The error amplifier compares this reference with the feedback voltage and amplifies the difference. If the feedback voltage is lower than the reference voltage, the pass-transistor gate is pulled low. This allows more current to pass to the output and increases the output voltage. If the feedback voltage is too high, the pass transistor gate is pulled high, allowing less current to pass to the output. Internal P-Channel Pass Transistor The AS1361/AS1362 feature a 0.5Ω (typ) P-channel MOSFET pass transistor, which provides several advantages over similar designs using a PNP pass transistor, including prolonged battery life. The P-channel MOSFET does not require a base driver, thus quiescent current is dramatically reduced. The AS1361/AS1362 LDOs do not exhibit prob- lems associated with typical PNP-based LDOs, and consume only 40µA of quiescent current in light load and 220µA in dropout (see Typical Operating Characteristics on page 6). Output Voltage The AS1361/AS1362 deliver preset output voltages from 1.5 to 4.5V, in 50mV increments (see Ordering Information on page 14). Shutdown The AS1361/AS1362 feature a low-power shutdown mode that reduces quiescent current to <200nA. Driving SHDNN low disables the internal voltage reference, error amplifier, gate-drive circuitry, and P-channel MOSFET pass transistor (see Figure 18), and the device output enters a high-impedance state. Note: For normal operation connect pin SHDNN to pin IN.www.austriamicrosystems.com Revision 1.03 9 - 15

All current moves in switching devices with the proper selection of amp rating capability. I chose these to do a job that had to handle only 1/3 of it's rated capacity. So they were the perfect choice. To date they work as expected; perfectly.
