LP2985AIM5-3.1/NOPB TI LDO Regulator | SOT-23-5 | 3.1V Output, 150mA

Product Overview

The LP2985AIM5-3.1/NOPB is a high-performance low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed output voltage of 3.1V with a maximum output current of 150mA. Housed in a compact SOT-23-5 package, this device is ideal for space-constrained applications requiring low noise and high power supply rejection ratio (PSRR). The LP2985AIM5-3.1/NOPB features a dropout voltage of typically 300mV at full load, making it suitable for battery-powered systems where efficiency is critical. With an operating input voltage range from 2.5V to 16V, it provides flexibility for various power supply designs. The device includes built-in protection features such as thermal shutdown and current limiting, ensuring reliable operation under fault conditions.
