LD2985
LD2985 is VERY LOW DROP AND LOW NOISE VOLTAGE REGULATOR manufactured by Unisonic Technologies.
UNISONIC TECHNOLOGIES CO., LTD
LINEAR INTEGRATED CIRCUIT
VERY LOW DROP AND LOW NOISE VOLTAGE REGULATOR LOW ESR CAP. PATIBLE, WITH INHIBIT FUNCTION
- DESCRIPTION
The UTC LD2985 is a 150m A 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 patible). 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=10n F, connected between bypass pin and GND reduce the noise to 30μVrms.
Typical applications are in cellular phone, palmtop laptop puter, personal digital assistant (PDA), personal stereo, camcorder and camera.
