TPS73633DRBT TI LDO Regulator | 8-SON(3x3) | 3.3V Output, 400mA

Product Overview

The TPS73633DRBT from Texas Instruments is a low-dropout (LDO) linear voltage regulator offering a fixed output voltage of 3.3V with a maximum output current of 400mA. Housed in a compact 8-SON (3x3 mm) package, this device is designed for space-constrained applications requiring high accuracy and low noise. The TPS73633DRBT features a typical dropout voltage of only 75mV at 400mA load, making it ideal for battery-powered systems. It also includes a logic-enabled shutdown mode to reduce quiescent current to less than 1µA.
