For noisy power supply application, suppress noise by adding ceramic capacitor between VCC and ground near the IC s VDD pad. The recommended capacitor value is 0.1µF. 2. For heavy loading application, it is recommended that an electrolytic capacitor is added between VCC and ground. The recommended capacitor value for button cell applications is 10µF. 3. The recommended value for button cell internal impedance is 750Ω or less. 4. The use of spring direct trigger is not recommended. If you must use such trigger, you need to add a ceramic capacitor between trigger pin and ground to debounce the spring noise. The recommend capacitor value is ~ 0.01 µf. Product Specification (V1.2) (This specification is subject to change without further notice)
