LM3881 Datasheet (Texas Instruments) - Simple Power Sequencer

LM3881, Simple Power Sequencer

The LM3881 Simple Power Sequencer offers the easiest method to control power up and power down of multiple power supplies (switching or linear regulators).

By staggering the start-up sequence, it is possible to avoid latch conditions or large inrush currents that can affect the reliability of the sy
