Explanation: Load regulation is defined as the change in output voltage for a change in load current and is also expressed in millivolts or as a percentage of output voltage. 9. An IC 7840 regulator has an output current =180mA and internal resistor =10Ω. Find the collector current in the output using the transistor specification: ß=15 and VEB(ON) =1.5v.
A. 270mA
B. 450mA
C. 100mA
D. 50mA
