Adjustable Output, Low-Ripple Power Supply
A 0.5 A output current capability power supply that
features an adjustable output voltage is shown in Figure 16.
This regulator delivers 0.5 A into 1.2 to 35 V output. The input
voltage ranges from roughly 3.0 to 40 V. In order to achieve
a 10 or more times reduction of output ripple, an additional
L–C filter is included in this circuit.
