Description

The LD2985 is a 150 mA fixed output voltage

regulator. 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 the board in

standby, decreasing the total power consumption.

An external capacitor, C

BYP

= 10 nF, connected

between bypass pin and GND reduces the noise
