UTC 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

SOT-25

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 application are in cellular phone, palmtop

laptop computer, personal digital assistant (PDA),

personal stereo, camcorder and camera.

Control switch ON/OFF.

Inhibit is not internally

pulled-up; it cannot be left

INHIBIT floating. Disable the device

when connected to GND or

to a positive voltage less

than 0.18V

VERSION)

*LOW OUTPUT NOISE VOLTAGE 30μVrms

Bypass Pin: Capacitor to

be connected to GND in

Bypass order to improve the

thermal noise

performances.
