PROCEDURE (Adjustable Output Voltage Versions)

EXAMPLE (Adjustable Output Voltage Versions)

5. Input Capacitor (C

IN) An aluminum or tantalum

electrolytic bypass capacitor located close to the regulator is

needed for stable operation.

5. Input Capacitor (C

IN) A 100 µF aluminum electrolytic

capacitor located near the input and ground pins provides

sufficient bypassing.

To further simplify the buck regulator design procedure, National Semiconductor is making available computer design software to

be used with the Simple Switcher line of switching regulators. Switchers Made Simple (version 3.3) is available on a (31⁄2")

diskette for IBM compatible computers from a National Semiconductor sales office in your area.
