LP2980IM5-3.3 TI LDO Regulator | SOT-23-5 | 3.3V Output, 50mA

Product Overview

The LP2980IM5-3.3 is a high-performance low-dropout (LDO) voltage regulator from Texas Instruments (TI), designed to deliver a fixed 3.3V output with a maximum output current of 50mA. Housed in a compact SOT-23-5 package, this device is ideal for space-constrained applications requiring low noise and low quiescent current. With a dropout voltage of only 120mV at 50mA load, it ensures efficient operation even when the input voltage is close to the output voltage. The LP2980IM5-3.3 features a shutdown mode that reduces quiescent current to less than 1µA, making it suitable for battery-powered devices. Its wide input voltage range of 2.5V to 16V provides flexibility for various power supply designs.
