Product Details
Item Description:
This auction is for one linear regulated power supply bare board (no parts). The board measures 4.25" long by 1.5" wide. It is set for +15V and -15V when using the attached BOM. While the regulators are designed for over 1A, this board is designed for up to 200mA for low power analog circuitry. More power can be handled by mounting the regulators off board on a larger heatsink. The BOM does not call out the heatsinks, any TO-220 heatsink should work, or for under 100mA no heatsink should be fine. The supplies can be set to other voltages by changing resistors or the potentiometers. This board mates up well with the AN-0115 dual winding 15VAC 10VA toroid transformer (not included) that provides two windings at 15VAC that can be configured as 30V center tapped. I have the assembled board in another listing. The BOM below is about $11.85 at Digi Key.
