APPLICATION NOTES

Minimum load

The minimum load to meet datasheet specification is 10% of the full rated load across the specified input voltage range. Lower than 10% minimum loading will result in

an increase in output voltage, which may rise to typically double the specified output voltage if the output load falls to less than 5%.

Capacitive loading and start up

Typical start up times for this series, with a typical input voltage rise time of 2.2μs and output capacitance of 10μF, are shown in the table below. The product

series will start into a capacitance of 47μF with an increased start time, however, the maximum recommended output capacitance is 10μF.

The voltage tolerance envelope shows typical load regulation characteristics for this product series. The tolerance envelope is the maximum output voltage variation due to

changes in output loading.

RoHS COMPLIANCE, MSL AND PSL INFORMATION

This series is compatible with RoHS soldering systems and is also backward compatible with Sn/Pb soldering systems.

The NTE series has a process, moisture, and reflow sensitivity classification of MSL1 PSL R7F as defined in J-STD-020

and J-STD-075. This translates to: MSL1 = unlimited floor life, PSL R7F = Peak reflow temperature 245°C with a

limitation on the time above liquidus (217°C) which for this series is 60sec max. The pin termination finish on this product

series is Gold with a plating thickness of 0.05 microns minimum.
