FAQ

How can the output noise be reduced?

Add a 1μF capacitor to the NR pin for wideband noise reduction. Larger values do not significantly improve noise performance.

What is the purpose of the TRIM pin?

The TRIM pin allows external adjustment of the output voltage by connecting a potentiometer between OUT and GND, enabling approximately ±1% adjustment.

Is the device stable with capacitive loads?

Yes, the device remains stable with capacitive load values ranging from 0μF to 100μF across all load current conditions.
