In the shunt regulator of fig below the Vz = 8.2 V and VBE

Home » Analog Electronic Circuits » Analog electronics circuits miscellaneous » Question

In the shunt regulator of fig below the V_z = 8.2 V and V_BE = 0.7 V. The regulated output voltage V₀ is:

1. 11.8 V
2. 7.5 V
3. 12.5 V
4. 8.9 V

Correct Option: D

From given figure
V₀ = V_Z + V_BE = 8.2 + 0·7 = 8·9 V
