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 V
between the VOUT pin and VSS pin.
The structure of the ON/OFF pin is as shown in Figure 14. 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 V
logic type is “A” and to the VIN pin if it is “B”.
