LP3961EMPX-2.5/NOPB TI LDO Regulator | SOT-223-5 | 2.5V Output, 800mA

Product Overview

The LP3961EMPX-2.5/NOPB is a high-performance low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed output voltage of 2.5V with a maximum output current of 800mA. Housed in a compact SOT-223-5 package, this device offers excellent line and load regulation, making it ideal for power-sensitive applications. The LP3961 features a low dropout voltage of typically 240mV at full load, enabling efficient operation even when the input voltage is close to the output. With a wide input voltage range from 2.5V to 7V, it provides flexibility for various power supply designs. The device includes built-in protection features such as overcurrent limiting and thermal shutdown, ensuring reliable operation under fault conditions.
