3. Shutdown pin (ON/OFF pin) (S-1701 Series A/B/C/D/E/F/G/H/J/K/L/M types)
This pin starts and stops the regulator.
When the ON/OFF pin is set to the shutdown level, the operation of all internal circuits stop, 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. At this time, the current consumption equals that consumed by the detector block, because the internal
circuits of the detector are operating. The VOUT pin becomes the VSS level due to the internally divided resistance of
several hundred k
Ω between the VOUT pin and VSS pin.
The structure of the ON/OFF pin is as shown in Figure 35. 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 as follows according to the
product type.
S-1701 Series A/B/C/D/E/F types:
Connect to the VIN pin.
S-1701 Series G/H/J/K/L/M types:
Connect to the VSS pin.
