LD2985

LINEAR INTEGRATED CIRCUIT

VERY LOW DROP AND LOW

NOISE VOLTAGE REGULATOR

LOW ESR CAP. COMPATIBLE,

WITH INHIBIT FUNCTION



DESCRIPTION

The UTC LD2985 is a 150mA 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 1μA 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=10nF, connected between bypass

pin and GND reduce the noise to 30μVrms.

Typical applications are in cellular phone, palmtop laptop

computer, personal digital assistant (PDA), personal stereo,

camcorder and camera.


