Description
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 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.
