I have designed the circuit of a voltage regulator. It is here:
I persume that you know that there aer some limitations on the old
3-terminal IC voltage regulators. 1) Needs about 2V or so Vin-Vout to operate. 2) Your bottom regulator is seeing twice the input voltage compared to what the top one sees; make sure the worst case input voltage is no more than 35V (if i remember correctly). 3) Worst of all, none are speced to pass more than one amp. However that can be fixed via the use of a power pass transistor connected to the regulator. The method may be found in older data sheets; all of the really cool stuff seems to have been dropped form the data sheets over the years (since the 80's).
the
factor>=150.
This is a JOKE? Right?
The input is shorted!
I read in sci.electronics.design that Clarence_A wrote (in ) about 'Voltage regulator', on Sat, 26 Mar 2005:
A lot of people make that mistake. You CAN'T run two bridge rectifiers with opposite polarity outputs from one transformer secondary winding. It result in two parallel, back-to-back diodes directly across the winding, BANG!!!
If you have only one winding available, it's quite OK to use half-wave rectification, with doubled-value filter capacitors. There is no net DC in the winding.
