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.
quiescent current is less than 1μA when INHIBIT
In
sleep
mode
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
to 30μVrms.
Typical application are in cellular phone, palmtop/
laptop computer, personal digital assistant (PDA),
personal stereo, camcorder and camera.
