LP38693MPX-1.8/NOPB TI LDO Regulator | SOT-223-5 | 1.8V Fixed Output, 500mA

Product Overview

The LP38693MPX-1.8/NOPB is a low-dropout (LDO) linear 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 low noise and high power supply rejection ratio (PSRR). The LP38693 features a low dropout voltage of typically 250mV at full load, enabling efficient operation even when the input voltage is close to the output. With an enable pin for power sequencing and thermal shutdown protection, it provides reliable performance in various electronic systems.
