At that point, the output current becomes constant and the output voltage drops in proportion to further increase in load. A variable power supply is one which facilitates the user to vary and adjust the desired output voltage and output current. 3v, 1A, i need the output current is 2A or 4A with 3. 20 ms < 4s. Whenever power supplies or converters are operated in a parallel configuration — whether for higher output power, fault tolerance, or both — current sharing is an important consideration. Outputs are connected together and each supply “shares” the load current. 9, which results in an a DC output power of Pdco= Po x0,8x0. 5 in stock. The regulator ensures the output voltage will always stay at the rated value of the power supply, regardless of the current that the device is consuming. 72= 3. Notes Although the 78xx series of voltage regulators are available with different current outputs, you can boost the available current output with this circuit.
