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

Product Overview

The LP2981A-50DBVR 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-50DBVR features a low quiescent current of 600µA (typical) and a shutdown mode that reduces current to 0.01µA, making it ideal for battery-powered systems. Its wide input voltage range of 2.5V to 16V provides flexibility for various power supply designs.
