Typical Applications
Bypass capacitors are necessary for stable operation of the
LM79XX series of regulators over the input voltage and
output current ranges. Output bypass capacitors will improve
the transient response by the regulator.
The bypass capacitors, (2.2µF on the input, 1.0µF on the
output) should be ceramic or solid tantalum which have good
Load and line regulation

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.
