LP3985IM5-3.2/NOPB TI LDO Regulator | SOT-23-5 | 3.2V Output, 150mA

Product Overview

The LP3985IM5-3.2/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed 3.2V output with a maximum 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 features a low quiescent current of 1.5µA (typical) in shutdown mode, extending battery life in portable devices. It also includes overcurrent and thermal shutdown protection for enhanced reliability.
