Features

* FlexCap: Stable with ceramic, tantalum, or aluminum
* capacitors Stable with 10 µF input/output capacitor Adjustable output voltage from 0.6V to 5V Low ground pin current 25 nA quiescent current in shutdown mode Guaranteed output

Applications

* Developed on a CMOS process, (utilizing a PMOS pass transistor), the LP38501/3 has low quiescent current that changes little with load current. Ground Pin Current: Typically 2 mA at 3A load current. Disable Mode: Typically 25 nA quiescent current when the Enable pin is pulled low. Simplified Compen
