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, CBYP=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.
