LP2980AIM5X-3.0/NOPB

LP2980AIM5X-3.0/NOPB Description

The LP2980AIM5X-3.0/NOPB is a low-dropout (LDO) linear voltage regulator from Texas Instruments, designed to deliver a fixed 3V output with a maximum output current of 50mA. This surface-mount device operates with an input voltage range up to 16V, making it suitable for a variety of power management applications. It features a low dropout voltage of 0.22V at 50mA, ensuring efficient regulation even when the input voltage is close to the output level. The regulator is housed in a SOT-23-5 package, optimized for space-constrained designs. With low quiescent current (95 µA) and high PSRR (63dB at 1kHz), it provides stable performance in noise-sensitive environments.
