TPS7301QDR TI Low-Dropout Regulator | 8-SOIC | 200mA, 1.22V to 5.5V

Product Overview

The TPS7301QDR from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for applications requiring low noise, high PSRR, and low quiescent current. It delivers up to 200 mA output current with a dropout voltage of typically 120 mV at full load. The output voltage is adjustable from 1.22 V to 5.5 V using an external resistor divider. The device features a shutdown mode that reduces quiescent current to less than 1 µA. It is available in the 8-pin SOIC package and is characterized for operation over the junction temperature range of –40°C to +125°C.
