Voltage regulators
Voltage regulator circuits are connected in power supplies between
the filter output and the load resistance. Figure 14.12 shows one of
the most common regulator circuits consisting of a series resistor R$
and a zener diode. The circuit works on the principle that the
current flowing through the diode, /
D
, can vary considerably with
very little change in the voltage across the diode, and hence across
the load R
L
. If the load current increases or decreases, the current
through the diode will decrease or increase by the sam ...
