LD2985

SERIES

VERY LOW DROP AND LOW NOISE VOLTAGE REGULATOR

LOW ESR CAP. COMPATIBLE, WITH INHIBIT FUNCTION

■

VERY LOW DROPOUT VOLTAGE (280mV

AT 150mA AND 7mV AT 1mA LOAD)

VERY LOW QUIESCENT CURRENT (2mA

TYP. AT 150mA LOAD AND 80µA AT NO

LOAD)

■

OUTPUT CURRENT UP TO 150mA

LOGIC CONTROLLED ELECTRONIC

SHUTDOWN

■

OUTPUT VOLTAGE OF 1.5, 1.8, 2.5, 2.8,

2.85, 3, 3.1, 3.2, 3.3, 3.5, 3.6, 3.8, 4, 4.7, 5V

INTERNAL CURRENT AND THERMAL LIMIT

AVAILABLE IN ± 1% TOLLERANCE (AT 25°C,

A VERSION)

SOT23-5L

■

LOW OUTPUT NOISE VOLTAGE 30µVrms

SMALLEST PACKAGE SOT23-5L

TEMPERATURE RANGE: -40°C TO 125°C

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.

DESCRIPTION

An external capacitor, C

=10nF, connected

BYP

The 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

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.
