TPS77333DGKR TI Linear Regulator | 8-VSSOP | 3.3V Output, 250mA

Product Overview

The TPS77333DGKR 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 250mA. Housed in a compact 8-pin VSSOP package, this device offers excellent line and load regulation, making it suitable for noise-sensitive applications. The TPS77333 features a low dropout voltage of typically 170mV at full load, enabling efficient operation even when the input voltage is close to the output. It also includes a logic-level enable pin for power sequencing and a built-in thermal shutdown and current limit for protection.
