TPS73433TDDCRQ1 TI LDO Regulator | SOT-23-THIN | 3.3V Output, 250mA

Product Overview

The TPS73433TDDCRQ1 is a low-dropout (LDO) linear voltage regulator from Texas Instruments, designed for automotive and industrial applications. It provides a fixed output voltage of 3.3V with a maximum output current of 250mA. The device is housed in a compact SOT-23-THIN package, making it suitable for space-constrained designs. With a low dropout voltage of typically 130mV at full load, it ensures efficient operation even when the input voltage is close to the output. The TPS73433TDDCRQ1 features high accuracy, low quiescent current, and excellent transient response, making it ideal for powering sensitive analog and digital circuits.
