TPS78228DDCT TI LDO Regulator | SOT-23-THIN | 2.8V Output, 150mA

Product Overview

The TPS78228DDCT is a low-dropout (LDO) linear voltage regulator from Texas Instruments, offering a fixed output voltage of 2.8V with a maximum output current of 150mA. Housed in a compact SOT-23-THIN package, this device is designed for space-constrained applications requiring low quiescent current and high accuracy. With a dropout voltage as low as 130mV at full load, it ensures efficient operation even under low input-to-output voltage differentials. The TPS78228DDCT integrates thermal shutdown and current limit protection, making it a reliable choice for power-sensitive designs.
