Moreover, if the output voltage adjusting resistor R 5 is a chip resistor. , The plug becomes compact. Further, if the output voltage adjusting resistor is a volume, then the plug need not be replaced, any output voltage can be set steplessly, and the replacement plug is unnecessary, which is economical.
