The UTC LD2985 is a 150mA fixed output voltage regulator. The
ultra low drop voltage and the low quicent current make them
particularly suitable for low noise, low power applications, and in battery
powered systems. In sleep mode quicent current is ls 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, CB=10nF, connected between b pin
and GND reduce the noise to 30μVrms.
Tical applications are in cellular phone, palm lap computer,
personal dial istant (PDA), personal stereo, camcorder and
camera.
