TPS73131DBVT TI LDO Regulator | SOT-23-5 | 3.1V Fixed Output, 150mA

Product Overview

The TPS73131DBVT from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed to deliver a fixed 3.1V output with a maximum current of 150mA. Housed in a compact SOT-23-5 package, this device offers excellent line and load regulation, making it ideal for space-constrained applications requiring a stable and noise-free power supply. With a dropout voltage as low as 30mV at 150mA, the TPS73131DBVT ensures efficient operation even when the input voltage is close to the output voltage. The device also features a low quiescent current of 40µA, which extends battery life in portable electronics.
