LP2960 Adjustable Micropower 0.5A Low-Dropout Regulators April 1999 LP2960 Adjustable Micropower 0.5A Low-Dropout Regulators General Description The LP2960 is a micropower voltage regulator with very low dropout voltage (12 mV typical at 1 mA load and 470 mV typical at 500 mA load) and very low quiescent current (450 µA typical at 1 mA load). The LP2960 is ideally suited for battery-powered systems: the quiescent current increases only slightly at dropout, which prolongs battery life. The LP2960 retains all the desirable characteristics of the LP2953, and offers increased output current. The error flag goes low any time the output drops more than 5% out of regulation. Reverse battery protection is provided. The LP2960 requires only 10 µF of output capacitance for stability (5V version).
