Transformer Selection
A mains transformer is not supplied with
this kit. The choice of transformer depends upon the voltage
range that the regulator will be used at. It is recommended that
the transformer voltage is slightly higher than the maximum output
voltage required from the regulator. For example, if the kit
is to be used to give an output voltage of 5-10v, it would be
advisable to use a 12v transformer. Higher voltages could be
used but this would lead to higher power dissipation in the regulator
which would require an additional heatsink.
