A voltage regulator in the form of a step-down converter, made by SparkFun. The AP63203 converter is designed to change the input voltage from 3.8 V to 32 V to the output: 3,3 V. Its current capability is 2 A with a fully integrated 125 mΩ MOSFET on the high side and a 68 mΩ MOSFET on the low side, providing highly efficient DC-DC conversion. All components are housed on a low-profile board and enclosed in a TSOT26 enclosure. Voltage Input/output can be provided via holes with marked leads, where you can solder e.g. goldpin pins.
