>> I am trying to make a +/- 5v dual rail power supply for this digital volume control IC: PGA2311 - Datasheet, and other devices such as a 741 op-amp. <<
I belive i will only need about 50mA for these devices ?
I would like to use these regulators to regulate the output of my power supply:
L7805 Positive Regulator - Data sheet
and KIA7905PI Negative Regulator - Datasheet
I have found this transformer: **broken link removed**, will this be ok for what i need ?
What sort of rectifier will i need ? and What sort of smoothing capacitors will i need ?
How should i fuse the power supply ? Should i fuse it before and after the transformer ? What value fuse should i use 1A ? or smaller ?
>Any suggestions are much appreciated<
