LP2981A-50DBVT TI LDO Regulator | SOT-23-5 | 5V Output, 100mA

Product Overview

The LP2981A-50DBVT is a high-performance low-dropout (LDO) voltage regulator from Texas Instruments, offering a fixed 5V output with a maximum output current of 100mA. Housed in a compact SOT-23-5 package, this device is designed for space-constrained applications requiring low noise and high accuracy. With a dropout voltage of only 200mV at full load, it ensures efficient operation even when the input voltage is close to the output. The LP2981A-50DBVT features a wide input voltage range from 2.5V to 16V, making it suitable for battery-powered systems, industrial controls, and automotive electronics. Its low quiescent current (typically 1.2mA) and shutdown capability (less than 1μA) further enhance power savings in portable devices.
