TPS77028DBVT TI LDO Regulator | SOT-23-5 | 2.8V Output, 50mA

Product Overview

The TPS77028DBVT from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for low-power applications. It provides a fixed output voltage of 2.8V with a maximum output current of 50mA. The device is housed in a compact SOT-23-5 package, making it ideal for space-constrained designs. With a dropout voltage of typically 35mV at 50mA load, it ensures efficient operation even with small input-to-output voltage differentials. The TPS77028DBVT features a low quiescent current of 17µA (typical), which extends battery life in portable devices. It also includes overcurrent and overtemperature protection for robust performance.
