FAQ

What is the function of the OUTF and OUTS pins?

OUTF provides the voltage reference force output, while OUTS serves as the voltage reference sense pin. Connecting these pins close to the load allows for remote sensing to compensate for voltage drops across PCB traces.

Is an output capacitor required for stability?

Yes, the MAX6033 requires a minimum output capacitance of 0.1µF for stability. It remains stable with capacitive loads up to 100µF.
