LP38693MP-1.8/NOPB TI LDO Regulator | SOT-223-5 | 1.8V Fixed Output, 500mA

Product Overview

The LP38693MP-1.8/NOPB is a low-dropout (LDO) voltage regulator from Texas Instruments, offering a fixed output voltage of 1.8V 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 efficiency and low noise. Its low dropout voltage (typically 250mV at full load) ensures stable operation even when the input voltage is close to the output, making it ideal for battery-powered systems. The LP38693 features a low quiescent current (30µA typical) and a shutdown mode that reduces current to less than 1µA, extending battery life in portable devices. With built-in overcurrent and thermal protection, it provides reliable performance in demanding environments.
