TPS70751PWPR Equivalent & Substitute Parts

Part Overview

The TPS70751PWPR is a linear voltage regulator IC from Texas Instruments designed for power management applications. It provides dual fixed output voltages (3.3V and 1.8V) with independent output currents of 250mA and 125mA respectively. The device is housed in a 20-HTSSOP surface mount package and is currently in active production status. Alternative equivalent parts may be required due to inventory constraints, supply chain considerations, or specific application requirements while maintaining identical electrical and mechanical specifications.
