Working Principles

The MIC2164YMM is a low dropout voltage regulator that regulates the output voltage with minimal voltage drop between the input and output. It operates by comparing the feedback voltage (FB) with a reference voltage (VREF) to control the output voltage. The enable pin (EN) allows the user to turn the regulator on or off.

When the input voltage (VIN) is within the specified range, the regulator maintains a stable output voltage (VOUT) by adjusting the internal pass transistor. The device also incorporates thermal shutdown and current limit protection to prevent damage under abnormal operating conditions.
