MIC2937A-12WU

MIC2937A-12WU is a linear voltage regulator designed for application in the automotive, industrial and consumer markets. It is the ideal solution for regulating the output voltage of a power source, providing a low dropout, low noise and low power dissipation capability. The MIC2937A-12WU features an adjustable output voltage range of 1.1V to 12.6V, making it ideal for applications requiring high accuracy and low power dissipation.

The MIC2937A-12WU is a three-terminal regulator with an input pin (VPin), an output pin (VPout) and a ground pin (GND). The VPin is the input voltage and is typically adjusted with a voltage divider to set the desired output voltage. The VPout is the output voltage of the regulator and is typically much lower than the VPin. The GND pin is the ground reference for the regulator and provides a low output impedance for efficient performance.

The MIC2937A-12WU is designed for both DC-DC and AC-DC applications. In DC–DC applications, it is used to convert a higher input voltage to a lower output voltage. In AC–DC applications, it is used to provide low noise and low dropout voltage conversion with good line and load regulation. The MIC2937A-12WU is rated to operate from an input voltage range of 9.0V to 18V DC.

The MIC2937A-12WU has several protection features including over current, short circuit and thermal protection. Furthermore, it has an integrated logic shut down protection feature which will shut off the output in the event of an output short circuit. This feature is important for applications that are not protected with external fusing or current limiting, as it will ensure that the output will remain disconnected from the power source until the short circuit is cleared.

The MIC2937A-12WU features a low quiescent current of 1.5 mA and a wide dynamic output current range of 0.3 mA to 12 A, making it suitable for low power applications such as battery powered devices, as well as high power applications such as motor drives and DC-DC converters. In addition, the MIC2937A-12WU features low output voltage ripple, making it ideal for applications requiring good output voltage accuracy.

The MIC2937A-12WU also features a wide temperature range of -40°C to +125°C, making it suitable for use in automotive and industrial environments. Furthermore, the MIC2937A-12WU is provided in a surface-mount TSOP-5 package, making it easy to incorporate into existing board designs.

The MIC2937A-12WU is suitable for a wide variety of applications, such as automotive applications, industrial applications, consumer electronics, battery powered devices, and DC to DC converters. It is the ideal solution for providing efficient, cost effective voltage regulation in a variety of applications.
