APPLICATION CIRCUIT

In the following application circuits:

*1 : For heavy loading application, adding an electrolytic capacitor between Vcc and Ground is recommanded.

The recommanded value for button cell application is 10µF.

*2 : The recommanded value for button cell application is 750

Ω or less.
