Figure 17.15 (a) Regulated power supply with dc input and dc output; (b) regulated 5 V dc. Power
supply with 230 V, 50 Hz ac supply as input.
Figure 17.16 Voltage regulator with adjustable output
Adjustable output voltage can be obtained by using two resistances in the
circuit as has been shown. We may use the input and output side capacitors in
the circuit. Voltage regulators are available either in plastic package or in
metal can package.
