LP2981AIM5-5.0/NOPB TI LDO Regulator | SOT-23-5 | 5.0V Output, 100mA

Product Overview

The LP2981AIM5-5.0/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed 5.0V output with a maximum 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 200mV at full load, it ensures efficient operation even when the input voltage is close to the output. The LP2981AIM5-5.0/NOPB features a low quiescent current of 600µA (typical) and a shutdown mode that reduces current to 0.01µA, making it suitable for battery-powered devices. Its output voltage accuracy is ±1.5% over temperature, load, and line variations. The device includes built-in protection features such as overcurrent and thermal shutdown, enhancing system reliability.
