A current project for myself, not for production, requires a bi-polar power supply, +/- 12 V, at about 100 mA on each supply.
I would like it to be fairly tightly regulated, and anticipated using +/- 12 V linear LDV regulators supplied by a +/- 15 V wall wart.
Having seen hundreds of various WW power supplies in catalogs I was rather suprised when I when looking,( Mouser, Jameco, Digikey), and had trouble finding a +/- 15 V WW, at ~ 100mA. I found only one, at $36 each.
I really don't wish to put a transformer in the case and suppply it with 120. A Murata mini-dip type PS is an option at about $15 each. I don't want to use two WWs, but that would be the least expensive option.
Other sources or thoughts would be appreciated.
