TPS73219DBVT TI LDO Regulator | SOT-23-5 | 1.9V Output, 250mA

Product Overview

The TPS73219DBVT from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for applications requiring a stable 1.9V output voltage. Housed in a compact SOT-23-5 package, it delivers up to 250mA of output current with excellent line and load regulation. The device features a low dropout voltage of typically 40mV at 250mA, making it ideal for battery-powered and portable electronics. Its high accuracy (±1% over temperature) and low quiescent current (typically 65μA) ensure efficient power management.
