Power Supply Regulators Unit 3 – Series Voltage Regulator
The voltage at the base of Q1 is more positive than the voltage at the emitter of Q1. VBE of Q1
is measured as shown.
NEW TERMS AND WORDS
series regulator - a voltage-regulating circuit that uses a series pass transistor.
pass transistor - a name commonly applied to a series regulating element because all output
current must pass through this device.
bleeder resistor - a resistor that is connected across a circuit to provide a minimum circuit load.
