The 3.3V-5V Voltage Regulator Board includes an on-board regulator that enables voltage to change from 3.3V to 5V with 250mA maximum output current. The board components are clearly marked so that there is no need for additional schematic.
The 3.3V Voltage Regulator Board features a monolithic control circuit MC34063A containing the primary functions required for DC-to-DC converters. The board receives 3.3V input voltage and converts it into a stable 5V DC output voltage. It is capable of delivering around 250mA maximum output current, which is suitable for most small electronic projects. Compact and inexpensive, this board is perfect for use when a 3.3V to 5V power source conversion is needed.
