Therefore, IC= 15×0.03 = 0.45A = 450mA. 10. How the average temperature coefficient of output voltage expressed in fixed voltage regulator?
A. miilivolts/oC
B. miilivoltsoC
C. None of the mentioned
D. oC/ miilivolts
Answer:A
Therefore, IC= 15×0.03 = 0.45A = 450mA. 10. How the average temperature coefficient of output voltage expressed in fixed voltage regulator?
A. miilivolts/oC B. miilivoltsoC C. None of the mentioned D. oC/ miilivolts
Explanation: The temperature stability or average temperature coefficient of output voltage, is the change in the output voltage per unit change in temperature and expressed in miilivolts/oC. 11. In the circuit given below, let VEB(ON)=0.8v and ß=16. Calculate the output current coming from 7805 IC and collector current coming from transistor Q1 for a load of 5Ω.
