TPS78928DBVR TI LDO Regulator | SOT-23-5 | 2.8V Output, 150mA

Product Overview

The TPS78928DBVR from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for space-constrained applications. It provides a fixed output voltage of 2.8V with a maximum output current of 150mA. The device is housed in a compact SOT-23-5 package, making it ideal for portable and battery-powered electronics. With a low dropout voltage of typically 120mV at 100mA load, it ensures efficient operation even when the input voltage is close to the output. The TPS78928DBVR features a quiescent current of only 17µA, extending battery life in standby modes. It also includes overcurrent and thermal shutdown protection for robust performance.
