6. APPLICATION CIRCUIT
In the following application circuits: *1: For noisy power supply application, adding a ceramic capacitor between VCC and ground near the IC's VDD pad is recommended. The recommend capacitor value is 0.1uF. *2: For heavy loading application, adding an electrolytic capacitor between VCC and ground is recommended. The recommended capacitor value for button cell applications is 10uF. EM55003S application circuit for EASY 1
