LP3855EMP-2.5/NOPB TI LDO Regulator | SOT-223-5 | 2.5V Output, 1.5A

Product Overview

The LP3855EMP-2.5/NOPB is a high-performance low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed 2.5V output with a maximum current of 1.5A. Housed in a compact SOT-223-5 package, this device offers excellent line and load regulation, making it ideal for power-sensitive applications. The LP3855 features a low dropout voltage of typically 280mV at full load, enabling efficient operation even when the input voltage is close to the output. With an enable pin for power sequencing and a built-in thermal shutdown and current limit protection, it ensures reliable performance in demanding environments.
