LP3874EMP-5.0/NOPB TI LDO Regulator | SOT-223-5 | 5V Output, 800mA

Product Overview

The LP3874EMP-5.0/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments, offering a fixed 5V output with a maximum output current of 800mA. Housed in a compact SOT-223-5 package, this device is designed for applications requiring low noise, fast transient response, and excellent line and load regulation. Its low dropout voltage (typically 240mV at 800mA) makes it ideal for battery-powered systems and post-regulation scenarios. The LP3874EMP-5.0/NOPB features a shutdown pin for power savings, output current limit, and thermal shutdown protection, ensuring reliable operation in demanding environments.
