It is recommended to install C3 to improve performance. C1 & C2 are required and should be installed as close to the converter as possible Model Number Nominal Output (V) AMSRL-783.3-NZ 3.3 AMSRL-7805-NZ 5 AMSRL-7812-NZ 12 AMSRL-7815-NZ 15 Vout Adjusted Up R2 (KΩ) Vout Adjusted Down R1 (KΩ) If it is needed to adjust the output voltage higher or lower than the converter’s nominal value use the equations in the table above to calculate appropriate resistor values, insuring that the voltage is within the adjustment range for the converter used. If no voltage adjustment is needed connect a 470uF ceramic capacitor from pin 6 to ground. NOTE: 1. Datasheets are updated as needed and as such, specifications are subject to change without notice.
