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

Product Overview

The LP2981A-28DBVR is a high-performance low-dropout (LDO) voltage regulator from Texas Instruments. It delivers 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). The LP2981A-28DBVR features a dropout voltage of only 120mV at full load, making it ideal for battery-powered systems where extended battery life is critical.
