Anda membutuhkan rangkaian regulator power supply yang dapat diatur output tegangannya mulai dari 1.2 to 15 V @ 3 A? Anda dapat mencoba rangkaian yang ada pada tulisan ini.  It uses Low Dropout Positive Regulator LM1084 in TO220 package for delivering variable output voltage…

• Input - 18 VAC/DC

• Output - variable output from 1.2 ~ 15 V @ 3 A Regulated low ripple DC voltage

• Heatsink for regulator IC

• On board bridge rectifier to convert AC to DC

• LED indication at input of IC

• Zener trimmed band gap reference, current limiting and thermal shutdown (provided by IC feature)

• Power Battery Terminal (PBT) for easy input and output connection

• Onboard PCB mounted Potentiometer (POT) for varying the output voltage

• Filter capacitors for low ripple DC output

• Four mounting holes of 3.2 mm each

• PCB dimensions 46 mm x 58 mm
