TPS73033DBVRM3 TI LDO Regulator | SOT-23-5 | 3.3V Output, 200mA

Product Overview

The TPS73033DBVRM3 is a low-dropout (LDO) linear voltage regulator from Texas Instruments, offering a fixed output voltage of 3.3V with a maximum output current of 200mA. Housed in a compact SOT-23-5 package, this device is designed for space-constrained applications requiring low noise and high power-supply rejection ratio (PSRR). The TPS73033DBVRM3 features a low quiescent current of 40 µA (typical) and a dropout voltage of only 120 mV at 200 mA, making it ideal for battery-powered and portable electronics.
