Performance Specications and Ordering Guide
Typical at TA = +25°C under nominal line voltage and full-load conditions. All models are
specied with an external 1F multi-layer ceramic and 10F capacitors across their output pins.
Ripple/Noise (R/N) measured over a 20MHz bandwidth.
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. (Load step = 50%.)
Nominal line voltage, no load/full load condition.
Add "N" or "P" to the part number for Remote Control Polarity. See Part Number Structure.
Contact DATEL for availability.
The surface-mount package (Case C40) is not yet available on all models. Consult DATEL.
