نظرة عامة على المنتج
The TPS73701DRVR is a 1A ultra-low-dropout voltage regulator from Texas Instruments with reverse current protection, packaged in a 6-pin WSON (DRV) package. It features an NMOS pass transistor architecture with a typical dropout voltage of 122 mV at 1A, adjustable output from 1.20V to 5.5V, and shutdown quiescent current below 20 nA. The device is stable with just a 1 µF ceramic output capacitor.
