Getting Started

To get started, connect the input voltage (between 2.1V and 6V) to the VIN pin, ground to the GND pin, and draw the regulated 3.3V from the VOUT pin. A bypass capacitor on the output is typically recommended for stability. Refer to the MCP1825S datasheet for recommended capacitor values and PCB layout guidelines.
