LP3982ILD-1.8/NOPB TI LDO Regulator | 8-WSON (3x2.5) | 1.8V Fixed Output, 300mA

Product Overview

The LP3982ILD-1.8/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments (TI). It provides a fixed output voltage of 1.8V 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 LP3982ILD-1.8/NOPB features a low dropout voltage of typically 120mV at full load, making it ideal for battery-powered systems. Its enable pin allows for power management, and the device includes overcurrent and thermal shutdown protection.
