LP2957, LP2957A 5V Low-Dropout Regulator for P Applications June 1998 LP2957, LP2957A 5V Low-Dropout Regulator for P Applications General Description The LP2957 is a 5V micropower voltage regulator with electronic shutdown, error flag, very low quiescent current (150 A typical at 1 mA load), and very low dropout voltage (470 mV typical at 250 mA load current). Output can be wired for snap-on, snap-off operation to eliminate transition voltage states where P operation may be unpredictable.
