When it uses the auxiliary power supply Uh, Itcanregulate output voltage low to U2 = 0.6 V(FIG. A). After Adjusted the potentiometer R8, itcan changethe load current of limitation whichmakes transistor loss powerless than its maximum allowable (FIG. B). The circuit of the main technical data:Technology data of the circuit: output voltage:U2=0.6V~15V output current:I2=2A~4A input voltage:U1=20.5V~30.8V internal resistance:Rg=40mΩ T1Radiator thermal resistance:Rthk≤0.64grd/W T2Radiator thermal resistance:Rthk≤10grd/W when ambient temperatureθu=0°C~60°C output voltage variable quantity: ΔU2=28mV when output current I2=0~4A(U1=constant,U2=15V), ΔU2=160mV input voltage U1=20.5~30.8V
