The MIC2940A-3.3BU TR is a low-dropout-voltage linear regulator (LDO). This type of voltage regulator uses the basic voltage divider concept of an open-loop design, where the output voltage is generated by using an adjustable resistor divider. The output voltage is determined by the ratio of the two resistors, and the amount of current that passes through them. The voltage regulator uses an internally adjustable voltage reference as the output voltage source, which provides a stable output voltage, even when the input voltage varies. The device also features over-current protection, over-temperature protection, and short-circuit protection.

The MIC2940A-3.3BU TR is a form, fit, and function compatible, three-pin device. This means it can easily be replaced in existing applications. The device has a maximum quiescent current rating of 25mA and operates from a temperature range between -55oC to +125oC. It also offers over-current, over-voltage, and short-circuit protection.
