3. Shutdown pin (ON/OFF pin)
This pin starts and stops the regulator.
When the ON/OFF pin is set to the shutdown level, the operation of all internal circuits stops, and the built-
in P-channel MOS FET output transistor between the VIN pin and VOUT pin is turned off to substantially
reduce the current consumption. The VOUT pin becomes the VSS level due to the internally divided
resistance of several M
Ω between the VOUT pin and VSS pin.
The structure of the ON/OFF pin is as shown in Figure 12.
Since the ON/OFF pin is neither pulled down
nor pulled up internally, do not use it in the floating state.
In addition, note that the current consumption
increases if a voltage of 0.3 V to VIN – 0.3 V is applied to the ON/OFF pin.
When the ON/OFF pin is not
used, connect it to the VSS pin if the logic type is “A” and to the VIN pin if it is “B”.
