Question 2 (2 points)d 18V 5.0V M1 STF80N10F7 R2 ?il 10kohm500ohm 12kohm Gnd The above linear regulator consists of an op-amp and source-follower buffer transistor, along with 500 ? trim potentiometer (pot), providing an adjustable output voltage Vo. Calculate the minimum value of the output voltage Vo with respect to ground to 3 significant figures. Be sure not to include units in the answer box, otherwise the error message "Field must be a valid number", appears when characters besides numbers are entered in the answer box.

Explanation / Answer

Question 2 - Minimum value of output is 10.712 Volts(when potentiometer's center pin is at the rightmost side, feedback resistance is minimum and input resistance is maximum so the gain(1+Rf/Rin) is lowest)

Question 3 - Maximum value of output is 11.25 Volts(when potentiometer's center pin is at the leftmost side, feedback resistance is maximum and input resistance is minimum so the gain(1+Rf/Rin) is highest)
