LP38693SDX-3.3/NOPB TI LDO Regulator | 6-WSON (3x3) | 3.3V Output, 500mA

Product Overview

The LP38693SDX-3.3/NOPB is a low-dropout (LDO) linear voltage regulator from Texas Instruments, offering a fixed output voltage of 3.3V with a maximum output current of 500mA. Housed in a compact 6-pin WSON package (3x3mm), it is designed for space-constrained applications requiring high accuracy and low noise. The device features a low dropout voltage of typically 120mV at full load, enabling efficient operation even when the input voltage is close to the output. With an enable pin for power sequencing and shutdown, it provides flexibility in power management. The LP38693SDX-3.3/NOPB is qualified for industrial and automotive applications, ensuring reliable performance over a wide temperature range.
