TLV74328PDBVR TI LDO Regulator | SOT-23-5 | 2.8V Output, 300mA

Product Overview

The TLV74328PDBVR is a low-dropout (LDO) linear voltage regulator from Texas Instruments, offering a fixed output voltage of 2.8V with a maximum output current of 300mA. Housed in a compact SOT-23-5 package, it is designed for space-constrained applications requiring high accuracy and low quiescent current. The device features a wide input voltage range from 1.4V to 5.5V, making it suitable for battery-powered and portable electronics. With a typical dropout voltage of only 130mV at 300mA load, it ensures efficient operation even under low input-to-output voltage differentials.
