56. Which is not considered as a linear voltage regulator?
57. A Schmitt trigger is a digital circuit that produce
58. The transistor shunt regulator shown in the figure has a regulated output voltage of 10 V, when the input varies from 20 V to 30 V. The relevant parameters for the zener diode and the transistor are: VZ = 9.5, VBE = 0.5 V, β = 99. Neglect the current through RB. Then the maximum power dissipated in the zener diode (PZ) and the transistor (PT) are
