LP2981A-28DBVT TI LDO Regulator | SOT-23-5 | 2.8V Output, 100mA

Product Overview

The LP2981A-28DBVT is a high-performance low-dropout (LDO) voltage regulator from Texas Instruments, offering a fixed output voltage of 2.8V with a maximum output current of 100mA. Housed in a compact SOT-23-5 package, this device is designed for space-constrained applications requiring low noise and high power supply rejection ratio (PSRR). Its low dropout voltage of typically 200mV at full load ensures efficient operation even when the input voltage is close to the output. The LP2981A-28DBVT is ideal for battery-powered devices, portable electronics, and noise-sensitive analog circuits.
