LP2957A Overview
The LP2957 is a 5V micropower voltage regulator with electronic shutdown, error flag, very low quiescent current (150 µA 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 µP operation may be unpredictable. Output crowbar (50 mA typical pull-down current) will bring down the...
