LP3985IM5-2.5/NOPB TI LDO Regulator | SOT-23-5 | 2.5V Output, 150mA

Product Overview

The LP3985IM5-2.5/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments, offering a fixed output voltage of 2.5V with a maximum output current of 150mA. Housed in a compact SOT-23-5 package, this device is designed for space-constrained applications requiring low noise and high power supply rejection ratio (PSRR). With a dropout voltage as low as 80mV at 150mA load, it ensures efficient operation even under low input-to-output voltage differentials. The LP3985 features a logic-compatible enable pin, thermal shutdown, and current limit protection, making it a reliable choice for powering sensitive analog and digital circuits.
