DESCRIPTION

The LD2982 is a 50mA 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碌A(chǔ) 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 30碌Vrms.

Typical application are in cellular phone, palmtop/

laptop computer, personal digital assistant (PDA),

personal stereo, camcorder and camera.
