LM3880 Three-Rail Simple Power Supply Sequencer

The LM3880 simple power supply sequencer offers the easiest method to control powerup sequencing and powerdown sequencing of multiple Independent voltage rails. By staggering the startup sequence, it is possible to avoid latch conditions or large in-rush currents that can affect the reliability of .

LM3880 Features

* Simple solution for sequencing three voltage rails from a single input signal

* Easily cascade up to three devices to sequence as many as nine voltage rails

* Powerup and powerdown control

* Tiny 2.9-mm x 1.6-mm footprint

* Low quiescent current: 25 µA
