TPS72728DSET TI LDO Regulator | 6-WSON (1.5x1.5) | 2.8V Output, 250mA

Product Overview

The TPS72728DSET from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for space-constrained applications. It offers a fixed output voltage of 2.8V with a maximum output current of 250mA. Housed in a compact 6-pin WSON package (1.5mm x 1.5mm), this device provides excellent line and load regulation, making it ideal for noise-sensitive circuits. The TPS72728DSET features a low dropout voltage of typically 130mV at full load, enabling efficient operation even when the input voltage is close to the output. It also includes a shutdown pin for power savings, with a typical quiescent current of 30µA in active mode and less than 1µA in shutdown.
