Application Circuit
The following notes apply to all conditions illustrated in the application diagrams below:
1.
For noisy power supply application, adding a ceramic capacitor between VDD
and ground is recommended. The recommend capacitor value is 0.1µF.
2.
For heavy loading application, adding an electrolytic capacitor between VDD and
ground is recommended. The recommended capacitor value for button cell
application is 10µF.
