Typical at TA = +25°C under nominal line voltage and full-load conditions, unless otherwise
noted. All models are tested and specied with external 22F tantalum input and output
capacitors. These capacitors are necessary to accommodate our test equipment and may
not be required to achieve specied performance in your applications. See I/O Filtering and
Noise Reduction.
Ripple/Noise (R/N) is tested/specied over a 20MHz bandwidth and may be reduced with
external ltering. See I/O Filtering and Noise Reduction for details.

These devices have no minimum-load requirements and will regulate under no-load conditions.
Regulation specications describe the output-voltage deviation as the line voltage or load is
varied from its nominal/midpoint value to either extreme.
Nominal line voltage, no-load/full-load conditions.
