The MIC2937A-12WU-TR is a linear voltage regulator designed by Micrel, Inc. The device is available in both a TO-220-5 and TO-263 package. It provides thermal protection, current protection and current limiting features, allowing it to be used in a wide range of applications ranging from battery regulation to general power regulation. The MIC2937A-12WU-TR also offers a high-performance adjustable output stage, which enables it to operate at a wide range of output voltages, from 0.7v to 18v. It has a maximum output current of 3A.

The MIC2937A-12WU-TR is ideally suited for applications such as automotive electronics, mobile phones, portable electronics, point-of-load converters, and battery charger applications. It provides output current protection against short-circuits, over-voltage protection, adjustable output voltage, and over-temperature protection. The adjustable output stage provides accurate regulation and high efficiency.

The working principle of this voltage regulator is based on the difference between the input voltage and the reference voltage. The reference voltage is produced using a band-gap reference circuit, and this reference voltage is then compared with the input voltage by an error amplifier. The output of the error amplifier is used to control the output voltage of the regulator. This is done by controlling the current drawn from the regulator’s output, thus changing the output voltage.

The MIC2937A-12WU-TR is a versatile voltage regulator and it can be used in a wide variety of applications. It provides the user with the flexibility to select the output voltage, output current, and thermal protection. It is a robust device, designed using advanced technologies, making it suitable for use in a wide range of situations. The device is particulary suitable for applications that require current limiting, such as battery regulation and point-of-load converters.
