Overvoltage Protection Circuit
In a constant-voltage power supply circuit output voltage may generally exceed the stipulated rating (equivalent to input
voltage) when the circuit is broken down or the IC and the printed circuit board is wrongly soldered. Therefore overvoltage
protection circuit is recommended to use to minimize the damages caused by the overvoltage.
