NOTE: 1. All models (excluding the 5 V dc input, D5) are also available in an extended temperature range of -40°C~85°C. For these
models, append “M” to the model number, e.g. PK15-D12-S3.3M.
2. Ripple & noise measured with a 20MHz bandwidth, off a 10uF electrolytic and a 0.1uF ceramic cap in parallel at the
ouptut.

APPLICATION NOTES
1. OUTPUT TRIMMING
The output voltages are preset to nominal values as indicated by the models table at the factory. If desired, the output voltage may
d
optionally be trimmed to a different value (+/- 10%) with external resistors and/or potentiometer as shown below.
