LM2937ES-12 Description

Short technical summary and product information.

The LM2937ES-12 from Texas Instruments is a 500mA low dropout linear voltage regulator with a fixed output voltage of 12V. It is designed to operate with an input voltage range from 6V to 26V, providing a stable output with a typical dropout voltage of 500mV at full load.

 

Key electrical characteristics include an output current capability of up to 500mA, a typical quiescent current of 2mA, and a PSRR of 57dB at 100KHz. The regulator incorporates internal protection features such as over-temperature, reverse polarity, and short circuit protection, along with 60V input transient protection.

 

This device is suitable for automotive and industrial control applications, as well as point-of-load regulation. It requires an output bypass capacitor and is stable with an ESR up to 3Ω. The LM2937ES-12 is available in a surface-mount TO-263-3 package.

 

Operating temperature range is from -40°C to 125°C. The output voltage is trimmed to within 5% tolerance under all operating conditions.
