Tangent Regulator, Adjustable, plus Diode bridge
NOTE: I am no longer offering pre-made circuit boards for this project. The reasons for this are many, and intertwined. Please do not email me asking me to change my mind on this. You are welcome to use the information here to build your own similar design.
Features of the TREAD design:
Very small board: 1.95" × 1.1" (approx. 5 cm × 3 cm)
Uncompromised performance
Works with any of the LM317 family regulators including the LDO variants. (LM1086, LT1085...)
Available as a kit or a professional circuit board, 1.5 oz copper
Two boards can be combined to make a dual supply (e.g. ±15 V)
Adjustable output voltage
Regulator at board edge to allow bolting board to large heat sinks
Accepts both AC and DC power sources
Produces smooth, linear-regulated DC power
