1.2 to 20 V, 3A power supply with LM350

1.2 to 20 V, 3A power supply

.This circuit use LM350 which is adjustable 3-terminal positive voltage regulators is capable of supplying in excess of 3A over a
1.2V to 33V output range. They are exceptionally easy to
use and require only 2 external resistors to set the output
voltage. Further, both line and load regulation are comparable
to discrete designs. Also, the LM150 is packaged in
standard transistor packages which are easily mounted and
handled.
