Quality Control: Learn More
Texas Instruments LM2937ET-12 is a positive fixed 12V linear voltage regulator. This device delivers a stable 500mA output current with a typical dropout voltage of 1V at 500mA. The input voltage range extends up to 26V, and it features internal protection against over-temperature, short-circuit conditions, mirror-image insertion, and transient voltages. With a quiescent current of 10mA and a maximum supply current of 20mA, this component is suitable for applications requiring efficient power regulation. The LM2937ET-12 is available in a TO-220-3 through-hole package, commonly utilized in automotive, industrial control, and consumer electronics power management systems.
