Working Principle

The ADM7154CP-3.3EVALZ is a linear voltage regulator with low dropout (LDO) capabilities. With its 0.8 V maximum voltage drop from the input to output, the board can provide a highly efficient and consistent power delivery. The board uses a power MOSFET to handle the voltage regulation; the main components of this power MOSFET being a p-type depletion-mode MOSFET (PMOS).

To provide dynamic control of the output voltage, the board includes an enable/disable circuitry composed of a PMOS device, a resistor, and a capacitor. This enables the PMOS device to turn off or on, connecting or disconnecting the output from the input when an appropriate voltage level is applied to the enable input of the PMOS. The combination of the enable/disable circuit, the power MOSFET, and the robust design of the board make the board highly reliable and efficient.
