LM3880 Overview
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 the system. Available in a 6-pin SOT-23 package, the simple sequencer contains a precision enable pin and three...
