LP3985IM5-2.9/NOPB TI LDO Regulator | SOT-23-5 | 2.9V Output, 150mA

Product Overview

The LP3985IM5-2.9/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed output voltage of 2.9V with a maximum output current of 150mA. Housed in a compact SOT-23-5 package, this device offers excellent line and load regulation, making it ideal for space-constrained and power-sensitive applications. With a low dropout voltage of typically 120mV at 150mA load, it ensures efficient operation even when the input voltage is close to the output. The LP3985 also features a low quiescent current of 30µA (typical) and a shutdown mode that reduces current consumption to less than 1µA, extending battery life in portable devices.
