LP3981ILDX-2.7/NOPB TI LDO Regulator | 6-WSON (3x4) | 2.7V Output, 300mA

Product Overview

The LP3981ILDX-2.7/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed output voltage of 2.7V with a maximum output current of 300mA. Housed in a compact 6-pin WSON package (3mm x 4mm), this device offers excellent line and load regulation, making it ideal for space-constrained and power-sensitive applications. The LP3981 features a low dropout voltage of typically 120mV at full load, ensuring efficient operation even when the input voltage is close to the output. With a quiescent current of only 30µA (typical), it is well-suited for battery-powered devices. The device also includes thermal shutdown and current limit protection for enhanced reliability.
