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.
Since the S-1135 Series A / B / E / F types have a built-in discharge shunt circuit to discharge the output
capacitance, the VOUT pin is forcibly set to VSS level. In the S-1135 Series C / D / G / H types, the VOUT pin is set
to VSS level through several hundred kΩ internal divided resistors between the VOUT and VSS pins. Note that the
current consumption increases when a voltage of 0.3 V to 1.0 V (Ta = 25
°C) is applied to the ON / OFF pin.
The ON / OFF pin is configured as shown in Figures 21 and 22.
In the S-1135 Series A / C / E / G types, the ON /
OFF pin is internally pulled up or pulled down to VSS when in the floating status, so the VOUT pin is set to the VSS
level.
In the S-1135 Series B / D / F / H types, the ON / OFF pin is not internally pulled up or pulled down, so do
not use these types with the ON / OFF pin in the floating status.
When the ON / OFF pin is not used in the S-1135
Series B / D / F / H types, connect the pin to the VIN pin in the B / D types, and connect it to the VSS pin in the F / H
types.

Note that the IC’s current consumption increases as much as current flows into the pull-up / pull-down
resistor when; the ON / OFF pin is connected to VIN in the A / C type, the ON / OFF pin is connected to
VSS in the E / G type (Figure 21).
