Voltage Margining
Output voltage margining can be implemented in the SLIN-03F2Ax modules by connecting a resistor, R_margin-up,
from the Trim pin to the ground pin for margining-up the output voltage and by connecting a resistor, R_margin-down,
from the Trim pin to output pin for margining-down. The figure below shows the circuit configuration for output
voltage margining.

Monotonic Start-up and Shutdown
The SLIN-03F2Ax modules have monotonic start-up and shutdown behavior for any combination of rated input
voltage, output current and operating temperature range.
Startup into Pre-biased Output
The SLIN-03F2Ax modules can start into a prebiased output as long as the prebias voltage is 0.5V less than the
set output voltage.
