3. Shutdown Pin (ON/OFF Pin)
4. Soft Start Function
Setting the ON/OFF pin to the Low level ("L") causes the voltage of the VOUT pin to change to the GND
level and simultaneously the operation of all the internal circuit to stop. At this time, the consumption
current is largely reduced, to a level of approximately 0.3 μA.
The structure of the ON/OFF pin is as shown in Figure 10. Since the ON/OFF pin is neither pulled
down nor pulled up internally, do not use it in the floating state.
When the ON/OFF pin is not used, connect it to the VIN pin.
The S-8821 Series features a built-in soft start circuit. Upon power application or when the
is switched from "L" to "H", the output voltage gradually rises over the soft start time, and the output
current is gradually output as a result. This soft start function reduces the input current rush.
