DCP020507: DCP020x Output voltage min/max versus Input Voltage Min/Max

Part Number: DCP020507

Hello

On page 3 of the DCP020507 datasheet in the device comparison table, it says that the output voltage @75% load will be within 5% of the nominal output voltage: 6.65-7.35V

This for an input voltage of 5V ± 10%.

1) How can the tolerance of the output voltage be smaller than the input voltage if the device is unregulated?

2) I made a few quick tests with DCP020507 and the relative output voltage error had more or less a 1:1 ratio with the input voltage error

How can this be explained? What am I missing?

Best regards

Haje

  • Hi Haje,

    The output voltage tolerance is spec'd at Vs (typ), not over the input voltage range.

    The line regulation spec in the electrical characterics table covers the tolerance if you are operating over the entire input voltage range.

    Thanks, Jason
