Working Principles

The MIC2506BM is a voltage regulator that maintains a stable output voltage regardless of fluctuations in the input voltage. It achieves this by using an internal reference voltage and feedback mechanism. The device compares the output voltage with the reference voltage and adjusts the internal circuitry to maintain the desired output voltage.

When the enable pin (EN) is high, the regulator is active and regulates the output voltage. Conversely, when the enable pin is low, the regulator enters a low-power standby mode, reducing power consumption.
