Fig. C: Configuration for programming output voltage.
Note that the tolerance of a trim resistor directly
affects
the
output
voltage
tolerance.
It
is
recommended to use standard 1% or 0.5%
resistors; for tighter tolerance, two resistors in
parallel
are
recommended
rather
than
one
standard value from Table 1.
The ground pin of the trim resistor should be
connected directly to the module GND pin (Pin 3)
with no voltage drop in between. Table 1 provides
the trim resistor values for popular output voltages.

The output voltage can also be programmed by an
external voltage source. To make trimming less
sensitive, a series external resistor (Rext) is
recommended between the TRIM pin and the
programming voltage source. The control voltage
can be calculated by the formula:
