LP3982IMM-3.3 TI LDO Regulator | 8-VSSOP | 3.3V Output, 300mA

Product Overview

The LP3982IMM-3.3 is a low-dropout (LDO) linear voltage regulator from Texas Instruments, designed to deliver a fixed 3.3V output with a maximum current of 300mA. Housed in an 8-pin VSSOP package, this device offers excellent line and load regulation, making it suitable for noise-sensitive applications. Its low dropout voltage (typically 120mV at 300mA) ensures efficient operation even when the input voltage is close to the output.
