Working Principles

The ADP2164ACPZ-2.5-R7 operates as a linear voltage regulator. It takes an input voltage (VIN) and regulates it to a stable output voltage (VOUT). The regulator uses internal circuitry to maintain the desired output voltage, even when the input voltage varies or there are fluctuations in the load.

The enable pin (EN) controls the operation of the regulator. When EN is high, the regulator is enabled and actively regulates the output voltage. When EN is low, the regulator enters a low-power standby mode, reducing power consumption.
