This popular power supply uses an L7805 voltage regulator IC together with bridge rectifier section and smoothing capacitors to provide a stabilised and regulated 5Vdc output of up to 500mA. Power-On LED indicator.
Ideal for powering many of the electronic kits that we sell or any other application where you need a stabilised 5Vdc supply.
As supplied without heatsink it is quite safe to draw 500mA continuously. This is a very conservative current rating as the circuit is capable of delivering 1 to 1.5A if the regulator IC is fitted with a suitable heatsink (e.g. Order Code HS-TO220 for loads of up to 1 Amp) and properly cooled. You would also need to up rate the input transformer accordingly.
Board requires a 5Vac, 0.5A transformer for standard operation (not included).
