Setpoint can be voltage programmable or programmed by a resistor divider. An internal 20kΩ from Vprog to 3.3Vdc is provided. Add a resistor to
complete the divider from Vprog to output_return.
4 Measured at the output with 0.1µf ceramic and a 10µf tantalum capacitor in parallel. 20mHz bandwidth limitation.
