3 Description
The LP2952 and LP2953 are micropower voltage
regulators with very low quiescent current (130 μA typical at 1-mA load) and very low dropout voltage
(typically 60 mV at light load and 470 mV at 250-mA
load current). They are ideally suited for battery•
powered systems. Furthermore, the quiescent current increases only slightly at dropout, which prolongs
battery life.
The LP2952 and LP2953 retain all the desirable
characteristics of the LP2951, but offer increased
output current, additional features, and an improved
shutdown function.
The automatic output discharge pulls the output down
quickly when the shutdown is activated.
The error flag goes low if the output voltage drops out
of regulation.
Reverse battery-input protection is provided.
The internal voltage reference is made available for
external use, providing a low temperature coefficient
(20 ppm/°C) reference with very good line (0.03%)
and load (0.04%) regulation.
