Universal power supply board for mounting any 78xx (sometimes L78xx, LM78xx, MC78xx...) series 3-terminal voltage regulator of your choice to make a regulated fixed DC voltage 1A maximum power supply.

The 78xx series regulators are available in fixed DC output voltages from 5 - 24Vdc, provide up to 1A load current and feature on-chip protection circuitry that simply shuts the chip down in the event of over heating or excessive current.

The input voltage can be unregulated AC (21V max) or DC (30V max) that is at least 2-3Vdc above the required output voltage for proper operation.

SELF-ASSEMBLY kit version (Order Code 3060KT) comprises a heatsink, 1A bridge rectifier, smoothing capacitors, LED power indicator, PCB mounted ON/OFF switch, input/output terminal blocks and a 2.5mm DC input jack socket. The user supplies the appropriate value L78xx series regulator from 5 to 24V (i.e. 7805, 7806, 7808, 7809, 7812, 7815, 7818, 7820, & L7824) for their needs.

PRE-ASSEMBLED versions (Order Codes AS3060-xx) are supplied complete with the appropriate value L78xx regulator.

Input Power Source: AC transformer (21Vac max) or regulated/unregulated DC (30Vdc max) with a current rating of at least 20% above the output load (up to 1 Amp max).

Heat Output, Efficiency & Suitability: Heat output generated by the regulator is proportional to the current drawn and the difference between the input and output voltage, e.g. an L7805 with 24V input and 1A load will get very hot, waste energy and alternative solutions could be considered (see L78xx datasheet below for more details).
