LD2981 Ultra low-drop voltage regulators

The LD2981 is a 100 mA fixed-output voltage regulator. The low-drop voltage and the ultra low quiescent current make them suitable for low noise, low power applications and in battery powered systems. The quiescent current in sleep mode is less than 1 μA when INHIBIT pin is pulled low. Shutdown logi.

LD2981 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
