Description	ULTRA LOW DROP-LOW NOISE BICMOS VOLTAGE REGULATORS
Datasheet	LD3985_STMicroelectronics.pdf

The LD3985 provides up to 150 mA, from 2.5 V to 6 V input voltage.

The ultra low drop voltage, low quiescent current and low noise make it suitable for low power applications and in battery-powered systems.

Regulator ground current increases slightly in dropout only, prolonging the battery life.

Input voltage from 2.5 V to 6 V.
Stable with low ESR ceramic capacitors.
Ultra low-dropout voltage (60 mV typ. at 150 mA load, 0.4 mV typ. at 1 mA load).
Very low quiescent current (85 µA typ. at no load, 170 µA typ. at 150 mA load; max.1.5 µA in OFF mode).
Guaranteed output current up to 150 mA.
Wide range of output voltages: 1.22 V; 1.8 V; 2.5 V; 2.7 V; 2.8 V; 2.9 V; 3 V; 3.3 V; 4.7 V.
Fast turn-on time: typ. 200 µs [CO = 1 µF, CB.
