TPS77733D TI LDO Regulator | 8-SOIC | 3.3V Output, 750mA

Product Overview

The TPS77733D from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed to deliver a fixed 3.3V output with a maximum output current of 750mA. Housed in an 8-pin SOIC package, this device offers excellent line and load regulation, making it suitable for a wide range of applications requiring a stable and accurate power supply. The TPS77733D features a low dropout voltage of typically 300mV at full load, enabling efficient operation even when the input voltage is close to the output voltage. It also includes built-in protection features such as overcurrent limiting and thermal shutdown, ensuring reliable performance under fault conditions.
