LP3985IM5X-3.3/NOPB TI LDO Regulator | SOT-23-5 | 3.3V Output, 150mA

Product Overview

The LP3985IM5X-3.3/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed 3.3V 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 also features a low quiescent current of 30µA (typical), which extends battery life in portable devices. Its stability with ceramic output capacitors simplifies design and reduces external component count.
