How well does the regulator hold the output voltage as the input voltage changes? The input voltage is a combination of VIN (DC source at 15V) and VS (AC sinewave currently set to 0V peak). A precision reference (zener diode) to set the output voltage. 1. HANDS-ON DESIGN Suppose youre asked to design a 12V regulator. For the simple transistor Q1 used, all of the default parameters are used except the current gain BF = 100. Run a simulation and check how much variation appears at V(2). What is the output voltage at V(2)?.

Actually there are more parameters than these four listed. Run a simulation. SIMULATION NOTE. However, many op amps can only deliver about 10mA! If Q1 is asking for more, you may need to get an op amp with more current output muscle or a transistor with greater current gain BF. To test the regulators line regulation, set VS to 1V peak by editing the VS statement to look like. How much base current is required during the 1A draw of the load? The op amp supplies this current to the transistor.

 

Set BF to a higher value like 200 and check IB(Q1) during the 1A load pulse. Current source IL generates a 1A pulse starting at 10ms and ending at 20ms. Three basic components are needed to achieve good voltage regulation. What causes these variations? One factor is the change in zener voltage V(4) due to a change at V(1). An automatic controller (opamp) to adjust the transistor drive. CIRCUIT INSIGHT Want to see the automatic controller (op amp) in action? Plot the Q1 base voltage V(3) to see the op amp increase the transistor on-voltage when the during the 1A pulse.You can also see the op amp achieve its prime directive of maintaining V- = Vz by plotting V(4) and V(5). CIRCUIT.
