General Description

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 output quickly when the regulator snaps off or when the shutdown function is activated.

Key Features

  • n 5V output within 1.4% over t.
