This power supply circuitis composed ofthe high definition integrated circuit μ A723 . The characteristics are as below: (1)The output voltage is adjustablein the range of 1.25~27 V. (2)Having current limiting safeguard function. While output current ≥ 6.5 A , the internal current limitingcircuit of μ A723turns onto protect voltage regulator. (3)The voltage stabilizes well, the currentis inthe range of0~4.5 A, output voltage changes 0.03 V.(4)Having short circuit indicating function.The short circuit indication oscillatoris composed of555 integrated circuit, when the output voltage exists, 555does notoscillation, LED is often bright, when there is no output voltage(output port short circuit), 555 generates oscillation, LED is shining with the frequencyin 0.5~1 Hzs.
