TYPICAL APPLICATIONS

Input bypass capacitors are recommended for stable operation of the OM7900 series of regulators over

the input voltage and output current ranges. Output bypass capacitors will improve the transient response

of the regulator.

The bypass capacitors, (2.2µF on the input, 1µF on the output) should be ceramic or solid tantalum which

have good high frequency characteristics. If aluminum electrolytics are used, their values should be 10µF

or larger. The bypass capacitors should be mounted with the shortest leads, and if possible, directly

across the regulator terminals.
