Product Introduction

Overview

The LM3880MFX-1AB/NOPB, produced by Texas Instruments (though originally developed by National Semiconductor), is a simple power supply sequencer designed to control the power-up and power-down sequencing of multiple independent voltage rails. This component is particularly useful in avoiding latch conditions or large in-rush currents that can affect system reliability. It is available in a compact 6-pin SOT-23 package, making it ideal for space-constrained applications.
