ULTRA LOW CURRENT CONSUMPTION, HIGH RIPPLE REJECTION AND LOW DROPOUT CMOS VOLTAGE REGULATOR
S-1167 Series
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 13. 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
VSS pin if the product type is “A” and to the VIN pin if it is “B”.
