LP38693MP-3.3/NOPB TI LDO Regulator | SOT-223-5 | 3.3V Fixed Output, 500mA

Product Overview

The LP38693MP-3.3/NOPB is a low-dropout (LDO) linear voltage regulator from Texas Instruments, offering a fixed 3.3V output with a maximum output current of 500mA. Housed in a compact SOT-223-5 package, this device is designed for space-constrained applications requiring high accuracy and low noise. With a dropout voltage of only 120mV at full load, it ensures efficient operation even when the input voltage is close to the output. The LP38693 features a wide input voltage range from 2.7V to 10V, making it suitable for various power supply designs. Its low quiescent current (55µA typical) and shutdown capability (less than 1µA) help extend battery life in portable devices.
