FEATURE DISCRIPTION

Output voltage trim function:

In this design,there is a trim pin that allows the customer to trim the output voltage to

nominal voltage.

In the schematic on page 2, R3, R14, R2 and external trim resistor (Rtrim) comprise the trim function

circuit. To trim-up, connect Rtrim between trim pin and GND. The Rtrim value is equal to:

Rtrim=
