LM2937ET-12 TI LDO Regulator | TO-220-3 | 12V Fixed Output, 500mA

Product Overview

The LM2937ET-12 from Texas Instruments is a fixed-output low-dropout (LDO) voltage regulator designed to deliver a stable 12V output with a maximum current of 500mA. Housed in a TO-220-3 package, this device offers excellent line and load regulation, making it suitable for a wide range of applications. With a dropout voltage of typically 0.5V at full load, it ensures efficient operation even when the input voltage is close to the output. The LM2937ET-12 includes built-in protection features such as overcurrent limiting and thermal shutdown, enhancing system reliability.
