Omnirel Corp => IRF 

OM7642SM - OM7644SM

TYPICAL PERFORMANCE CHARACTERISTICS

Input bypass capacitors are recommended for stable operation of the OM7642SM 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.
