Output Voltage Selection
The AS1363 is available in two versions
fixed output voltage and the other version can operate with a preset output voltage or with user-adjustable output volt-
ages (1.2V to 5.3V).

For the fixed output voltage version connect a capacitor C
performance
To use the factory preset output voltage of the user-adjustable output voltage version, connect pin SET to GND
(see Figure
For configurations using an output voltage other than the factory preset, a voltage-divider from OUT to SET to
GND is required, as shown in
