LM3880 Description
The LM3880 Power Sequencer offers the easiest method to control power up and power down of multiple power supplies (switchers or linear regulators). By staggering the startup sequence, it is possible to avoid latch conditions or large in-rush currents that can affect the reliability of the system. Available in a SOT23-6 package, the Power Sequencer contains a precision enable pin and three open drain output flags.
