LP3982ILD-3.3/NOPB TI LDO Regulator | 8-WSON (3x2.5) | 3.3V Output, 300mA

Product Overview

The LP3982ILD-3.3/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed 3.3V output with a maximum current of 300mA. Housed in an 8-WSON (3x2.5mm) package, this device offers excellent line and load regulation, making it ideal for noise-sensitive applications. With a dropout voltage of typically 120mV at 300mA, it ensures efficient operation even with low input-to-output voltage differentials. The LP3982ILD-3.3/NOPB features a low quiescent current of 85µA (typical) and a shutdown mode that reduces current to less than 1µA, extending battery life in portable devices. Its stable operation with ceramic output capacitors simplifies design and reduces external component count.
