• Manufacturer: XP Power Limited

8-3. Adjustable method for output voltage
e.g.
Keep Trim pin (3pin) OPEN, when using output voltage at 1.8V without adjusting. Output voltage
may be adjusted between 0.8 and 1.8V by connecting a resistor between Trim pin (3pin) and GND
pin (4pin).
Wiring for Trim pin should be short and straight preferably when using adjustable output voltage
feature. If noise appears on the pin, it causes mal-function.
The below formula for external resistance should be referred.
