Diagram (a) circuit's output voltage is adjusted by regulation resistor Rp, and ithas regulating characteristics . Diagram (b) is the relationship curve of output voltage bias ΔUAandload current IA (0~70mA), diagram (c) is the relationship curve of input voltage UE. Main technical data input voltage: UE=11~20V output voltage:UA=8~18V maximum output current: IA=70mA voltage regulation factor (ΔUE=1V, UE=15V, UA=10V, IA=40mA); F=ΔUA/UA=1×10-4 load regulation factor (IA=0~60mA, UE=15V, UA=10V); F=ΔUA/UA=4×10-4 dynamic resistance: Ri=60mΩ output voltage temperature coefficient: 3~5×10-5V/K
