LD1985
LINEAR INTEGRATED CIRCUIT
VERY LOW DROP AND LOW
NOISE VOLTAGE
REGULATOR LOW ESR CAP.
COMPATIBLE, WITH INHIBIT
FUNCTION
DESCRIPTION
The UTC LD1985 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 is in cellular phone, palmtop laptop
computer, personal digital assistant (PDA), personal stereo,
camcorder and camera.
