DESCRIPTION
The 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 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 are in cellular phone, palmtop laptop computer, personal digital assistant (PDA), personal stereo, camcorder and camera.

■ VERY LOW DROPOUT VOLTAGE (280mV AT 150mA AND 7mV AT 1mA LOAD)
■ VERY LOW QUIESCENT CURRENT (2mA TYP. AT 150mA LOAD AND 80µA AT NO LOAD)
