This circuit is an ususal linear three-terminal regulator expansion flow circuit. 1. Drawback of source; 1.1 The power supply is a linear regulator circuit, of which all have their own internal power loss, and voltage drops result in heat loss, and the low efficiency needs us pay special attention on heat issues. 1.2 As the working speed of core component in 7805 is not too high, it has slow response to rapid changes of the input voltage or load current; 1.3 This circuit does not increase the power protection circuit because 7805 itself has overcurrent and temperature protection.
