Regulator 15V 400mA by 748 and 2N3055

Thursday, September 25th, 2008

Today try come to see linear regulator 15volt 400mA Circuit. It is use IC op-amp IC748 perform control Voltage Regulator 15V. by have ZD1 5.1V be the referable voltage. For Transistor 2N3055 , perform enlarge current tallly go up and Q3-2N3904 help protect something through the circuit. This circuit can give Current get about 400mA [...]

Basic DC voltage Regulated 13V low current.
