Features

* Ultra low dropout voltage (0.17 V typ. at 100 mA load, 7 mV typ. at 1 mA load)
* Very low quiescent current (80 μA typ. at no load in on mode; max 1 μA in off mode)
* Guaranteed output current up to 100 mA
* Logic-controlled electronic shutdown
* Output voltage of 2.5; 3.0; 3.3

Applications

* and in battery powered systems. The quiescent current in sleep mode is less than 1 μA when INHIBIT pin is pulled low. Shutdown logic control function is available on pin n° 3 (TTL compatible). This means that when the device is used as local regulator, it is possible to put a part of the board in st
