LP38690DT-3.3/NOPB TI LDO Regulator | TO-252-3 | 3.3V Output, 1A Current

Product Overview

The LP38690DT-3.3/NOPB is a low-dropout (LDO) linear voltage regulator from Texas Instruments, offering a fixed output voltage of 3.3V and a maximum output current of 1A. Housed in a TO-252-3 (DPAK) package, this device is designed for applications requiring a stable and low-noise power supply. With a dropout voltage of typically 250mV at 1A load, it ensures efficient operation even when the input voltage is close to the output. The LP38690DT-3.3/NOPB features a wide input voltage range from 2.7V to 10V, making it suitable for various battery-powered and industrial systems. Its low quiescent current (typically 55µA) and shutdown capability (less than 1µA) help extend battery life in portable devices. The device also includes overcurrent and thermal shutdown protection for enhanced reliability.
