Unformatted text preview: to basically VC. Very small changers in the base- emitter voltage control the transistors output current and allow adjustment of the emitter current by slightly varying the voltage between the base and emitter of Q1. When the op- amp is combined with the pass transistor, the op- amp acts to adjust the output voltage VOUT so that it (or the fraction of it in the feedback circuit) always equals the reference voltage VREF supplied by the zener diode. Since the op- amp has essentially infinite gain, this will remain true even if the input voltage VC or the load RLOAD changes. For example, if the AC line voltage should decrease causing VC to decrease or if the load current increases, VOUT would normally decrease. However, when VOUT drops even a fraction...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
