The UTC 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 1
μA 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 30
μVrms.
Typical applications are in cellular phone, palmtop laptop
computer,
personal
digital
assistant
(PDA),
personal
stereo,
camcorder and camera.
