Note:

1. It is recommended that a 10uF or higher capacitor and a 100nF bypass capacitor are connected

between VDD and the closest VSS pin of the device.

2. For ensuring power stability, a 4.7uF or higher capacitor must be connected between LDO pin

and the closest VSS pin of the device. Also a 100nF bypass capacitor between LDO and VSS

help suppressing output noise.
