The output voltage can be adjusted in the range of -20%/+15%. 
To increase the output voltage, connect an external resistor between the 

TRIM-Pin and the negative output voltage (-Vout) and to decrease the voltage, 
connect the resistor between the TRIM-Pin and the positive output voltage 

(+Vout). 
Alternatively a 10k

Ω

 potentiometer can be used to adjust the output voltage 

continuously within its limits.
