3. 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.
4. For ensuring power stability, a 1uF 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
