Short Circuit Protection			Long term short circuit, automatic recovery

Notes:

①The testing method for ripple and noise adopts parallel line testing method

②When the load is below 10%, the maximum ripple and noise output of 3.3V/5V is 150mVp-p, and the maximum ripple and noise output of 9V/12V/15V is 2% Vo.
