Boardoza SPX1117 ADJ Adjustable LDO Regulator Breakout Board
This board is designed as an adjustable power module using the SPX1117M3-L/TR low-dropout (LDO) linear regulator. The default output voltage is configured as 5V. Additionally, 1.8V and 3.3V output levels can be selected through the resistor divider connected to the SPX1117 ADJ pin.
The SPX1117 supports up to 800 mA output current and features a typical 1.1 V dropout voltage, making it suitable for applications requiring a low input-to-output voltage difference. The board includes input and output capacitors as recommended by the manufacturer to ensure regulator stability.
The desired output voltage configuration is selected using the dedicated jumper/pad, allowing the board to be easily adapted to different system voltage requirements.
