The LP2953A is a micropower voltage regulator with very low quiescent current (130 μA typical at 1 mA load) and very low dropout voltage (typ. 60 mV at light load and 470 mV at 250 mA load current). It is ideally suited for battery-powered systems. Furthermore, the quiescent current increases only slightly at dropout, which prolongs battery life.
The LP2953A retains all the desirable characteristics of the LP2951, but offers increased output current, additional features, and an improved shutdown function.
The internal crowbar 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 protection is provided.
The internal voltage reference is made available for external use, providing a low-T.C. reference with very good line and load regulation.
