TPS781250200DDCT TI LDO Regulator | SOT-23-THIN | 2.5V, 200mA

Product Overview

The TPS781250200DDCT is a low-dropout (LDO) linear regulator from Texas Instruments, offering a fixed output voltage of 2.5V and a maximum output current of 200mA. Housed in a thin SOT-23 package (SOT-23-THIN), this device is designed for space-constrained applications requiring low quiescent current and high power-supply rejection ratio (PSRR). The TPS781 series features a wide input voltage range from 2.7V to 5.5V, making it suitable for battery-powered and portable electronics. With an ultra-low dropout voltage of typically 130mV at 200mA load, it ensures efficient operation even when the input voltage is close to the output. The device also includes thermal shutdown and current-limit protection for enhanced reliability.
