AP139 300mA LOW-NOISE CMOS LDO AP139 Rev. 6 1 of 7 FEBRUARY 2009 www.diodes.com © Diodes Incorporated Lead-free • Very Low Dropout Voltage • Low Current Consumption: Typ. 45μA, max. 60uA • Output Voltage: 1.5V, 1.8V, 2.0V, 2.5V, 2.8V, 3.0V 3.3V, and 3.5V • Guaranteed 300mA Output • Input Range from 2.7 up to 5.5V • Thermal Shutdown • Current Limiting • Stability with Low ESR Capacitors • Low Temperature Coefficient • Lead Free Package: SOT25 • SOT25: Available in “Green” Molding Compound (No Br, Sb) • Lead Free Finish/RoHS Compliant (Note 1) The AP139 is a positive voltage linear regulator utilizing CMOS technology. The features that include low quiescent current (45μA typ.), low dropout voltage, and high output voltage accuracy, make it ideal for battery applications. EN input connected to the device will produce a low bias current. The space-saving SOT25 package is attractive for “pocket” and “hand held” applications. This rugged device has both thermal shutdown, and current limit protections to prevent device failure under the “worst” operating conditions. In a low noise, regulated supply application, a 10nF capacitor is necessary to be placed in between Bypass and Ground. The AP139 is stable with a low ESR output capacitor of 1.0μF or greater. • Personal Communication Devices • Home Electric/Electronic Appliances • PC Peripherals • Battery-Powered Devices Output Voltage Package Packing W : SOT25 Lead Free G : Green 7 : Tape & ReelL : Lead Free AP139 - XX W X - 7 15 :1.5V 18 :1.8V 20 :2.0V 25 :2.5V 28 :2.8V 30 :3.0V 33 :3.3V 35 :3.5V Device Package Code Packaging (Note 2) 7” Tape and Reel Quantity Part Number Suffix AP139-XXWL-7 W SOT25 3000/Tape & Reel -7 AP139-XXWG-7 W SOT25 3000/Tape & Reel -7 Notes: 1.

The P-channel pass transistor receives data from the error amplifier, over-current protection, and thermal protection circuits. During normal operation, the error amplifier compares the output voltage to a precision reference. The over-current and thermal shutdown circuits become active when the junction temperature exceeds 130oC, or the current exceeds 300mA. During thermal shutdown, the output voltage remains low. Normal operation is restored when the junction temperature drops below 110oC. The AP139 switches from voltage mode to current mode when the load exceeds the rated output current. This prevents over-stress. Enable The enable pin normally floats high. When actively, pulled low, the PMOS pass transistor shuts off, and all internal circuits are powered down. In this state, the quiescent current is less than 2μA. This pin behaves much like an electronic switch. External Capacitor The AP139 is stable with a low ESR output capacitor to ground of 1.0μF or greater. It can keep stable even with higher ESR capacitors. A second capacitor is recommended between the input and ground to stabilize VIN. The input capacitor should be larger than 0.1μF to have a beneficial effect. All capacitors should be placed in close proximity to the pins. A “quiet” ground termination is desirable.
