LD1985

UNISONIC TECHNOLOGIES CO., LTD 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.  FEATURES * Very Low Dropout Voltage (280mV at 150mA ...
