LP3855EMP-3.3/NOPB TI LDO Regulator | SOT-223-5 | 3.3V Output, 1.5A

Product Overview

The LP3855EMP-3.3/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed 3.3V 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 noise-sensitive applications. The LP3855 features a low dropout voltage of typically 300mV at full load, enabling efficient operation even with small input-to-output voltage differentials. Its enable pin allows for power sequencing and shutdown control, while built-in protection features include overcurrent and thermal shutdown.
