3. ON / OFF pin
This pin starts and stops the regulator.
When the ON / OFF pin is set to the power-off level, the entire internal circuit stops operating, and the built-in P-
channel MOS FET output transistor between the VIN and VOUT pins is turned off, reducing current consumption
significantly.
Note that the current consumption increases when a voltage of 0.25 V to VIN
0.3 V is applied to the ON / OFF pin.
The ON / OFF pin is configured as shown in Figures 17 and 18.
3. 1 S-1312 Series A / C types
The ON / OFF pin is internally pulled down to VSS in the floating status, so the VOUT pin is set to the VSS level. For
the ON / OFF pin current, refer to the A / C type of ON / OFF pin input current “H” in “ Electrical Characteristics”.
3. 2 S-1312 Series B / D types
Do not use the ON / OFF pin in the floating state because this pin is internally not pulled up or pulled down. When
not using the ON / OFF pin, connect the pin to the VIN pin.
