TPS77128DGKR TI Linear Voltage Regulator | 8-VSSOP | 2.8V Output, 150mA

Product Overview

The TPS77128DGKR from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed to deliver a fixed output voltage of 2.8V with a maximum output current of 150mA. Housed in a compact 8-VSSOP package, this device offers excellent line and load regulation, making it ideal for noise-sensitive applications. The TPS77128DGKR features a low dropout voltage of typically 170mV at full load, enabling efficient operation even with small input-to-output voltage differentials. It includes built-in overcurrent and thermal shutdown protection, ensuring reliable performance under fault conditions.
