LP2981IM5-5.0 TI LDO Regulator | SOT-23-5 | 5.0V Output, 100mA

Product Overview

The LP2981IM5-5.0 from Texas Instruments is a high-performance, low-dropout (LDO) voltage regulator designed to deliver a fixed 5.0V output with a maximum output current of 100mA. Housed in a compact SOT-23-5 package, this device is ideal for space-constrained applications requiring low noise and high accuracy. With a dropout voltage of only 150mV at full load, the LP2981 ensures efficient operation even when the input voltage is close to the output. Its low quiescent current (1.2mA typical) and shutdown capability (0.01µA typical) make it suitable for battery-powered systems.
