LP3962EMP-3.3 TI LDO Regulator | SOT-223-5 | 1.5A, Fixed 3.3V Output

Product Overview

The LP3962EMP-3.3 is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed 3.3V output with a maximum output current of 1.5A. Housed in a compact SOT-223-5 package, this device offers excellent line and load regulation, making it ideal for noise-sensitive applications. With a dropout voltage as low as 240mV at full load, it ensures efficient operation even when the input voltage is close to the output. The LP3962EMP-3.3 incorporates protection features such as current limiting, thermal shutdown, and reverse battery protection, enhancing system reliability.
