Q: Can the MC 3603 S be used for AC voltage regulation?
A: No, the MC 3603 S is designed for DC voltage regulation only. Use a rectifier circuit to convert AC to DC before using the MC 3603 S.
Q: What is the maximum input voltage for the MC 3603 S?
A: The maximum input voltage is 40V. Exceeding this value may damage the component.
Q: Can I use the MC 3603 S without a heatsink?
A: Yes, but only for low current loads. For higher currents, a heatsink is recommended to prevent overheating.
Q: How do I calculate the resistor values for a specific output voltage?
A: Use the formula ( V_{OUT} = V_{REF} \times \left(1 + \frac{R_2}{R_1}\right) ), where ( V_{REF} ) is 1.25V. Select ( R_1 ) and ( R_2 ) accordingly.
This concludes the documentation for the MC 3603 S voltage regulator driver.
