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 only. วงจรจ่ายไฟตรงคงที่ ขนาด 15V ด้วยไอซีออบแอมป์ IC 748 และทรานซิสเตอร์ 2N3055 อ่านต่อ [...] [...] Today try come to see linear regulator 15volt 400mA Circuit.
