Working Principles

The MIC2772-M3S3YML-TR operates as a linear voltage regulator. It compares the output voltage with a reference voltage and adjusts the pass transistor accordingly to maintain a stable output voltage. When the input voltage is higher than the desired output voltage, the regulator reduces the voltage using a series pass element. Conversely, if the input voltage drops below the desired output voltage, the regulator increases the voltage to compensate.

Application Field Plans

The MIC2772-M3S3YML-TR finds application in various electronic devices, including but not limited to: - Mobile phones - Tablets - Portable media players - Wearable devices - IoT devices
