The output voltage of the circuit in Figure (a) is adjusted by the potentiometer Rp and has linear adjustment characteristics. Figure (b) shows the relationship between the output voltage deviation Ua and the load current Ia (0-70mA), and Figure (c) shows the relationship between the output voltage deviation Ua and the input voltage Ue.
Main technical data:
Input voltage: Ue=11~20V
Output voltage: Ua=8~18V
Maximum output current: Ia=70mA
Voltage regulation rate (Ue=1V, Ue=15V, Ua=10V, Ia=40mA);
Load regulation rate (Ia=0~60mA, Ue=15V, Ua=10V);
Dynamic internal resistance: R1=60m ohm
Temperature coefficient of output voltage : 3~5X10-5 V/K
