Overview
LD2985 Very low drop and low noise voltage regulator with inhibit function SOT23-5L Features • Very low dropout voltage (280 mV at 150 mA and 7 mV at 1 mA load) • Very low quiescent current (2 mA typ.
at 150 mA load and 80 µA at no load) • Output current up to 150 mA • Logic controlled electronic shutdown • Output voltage of 1.

The ultra low drop voltage and the low quiescent current make them particularly suitable for low noise, low power applications, and in battery powered systems.
In sleep mode quiescent current is less than 1 µA when INHIBIT pin is pulled low.
Shutdown logic control function is available on pin 3 (TTL compatible).
This means that when the device is used as local regulator, it is possible to put a part of ...
