3. ON / OFF pin
The ON / OFF pin controls the internal circuit and the output transistor in order to start and stop the regulator. When
the ON / OFF pin is set to OFF, the internal circuit stops operating and the output transistor between the VIN pin
and the VOUT pin is turned off, reducing current consumption significantly.
Note that the current consumption increases when a voltage of 0.8 V to VIN
− 0.3 V is applied to the ON / OFF pin.
The ON / OFF pin is configured as shown in Figure 21.
Since the ON / OFF pin is internally pulled down to the VSS pin in the floating status, the VOUT pin is set to the
VSS level.

*1. The constant value is output due to the regulating based on the set output voltage value.
*2. The VOUT pin voltage is pulled down to VSS due to combined resistance (RLOW = 3.0 k
Ω typ.) of the
discharge shunt circuit and the feedback resistors, and a load.
