LP3982ILDX-ADJ/NOPB TI LDO Regulator | 8-WSON (3x2.5) | 2.5V-6V Input, 300mA Output

Product Overview

The LP3982ILDX-ADJ/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments (TI). It offers an adjustable output voltage from 1.25V to 5.5V with a maximum output current of 300mA. Housed in an 8-pin WSON package (3mm x 2.5mm), this device is designed for space-constrained applications requiring low noise and high power supply rejection ratio (PSRR). The LP3982 features a low dropout voltage of typically 120mV at 300mA load, making it ideal for battery-powered systems. Its enable pin allows for power sequencing and shutdown control, reducing quiescent current to less than 1µA when disabled.
