Regulator tegangan multi output dengan delay.

Multi output voltage regulator using SMR88xx

Using SMR88xx we can make multi stage DC regulator with delay turn on with each of the stage.

C2, C3 and C4 is optional, internally SMR88xx has a decoupling ceramic capacitor, but you may want to add some filtering capacitor along the line.
For 3Amp you may use 1N5400 for forward diode, and 1N4001 for 1Amp current, this diode will function as protection circuit and a simple current limiter, alltough the best protection for current will be a fuse.
12V will on first, followed by 5V, when the 5V is on it will trigger the 3.3V to turn on.
