SUPER-SMALL PACKAGE 2-CIRCUIT HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR
S-1711 Series
4. Discharge shunt function (S-1711 Series A/ B/ E/ F types)
5. Pull-down/pull-up resistor (S-1711 Series A/ C/ E/ G types)
The S-1711 Series A/ B/ E/ F types have built-in discharge shunt circuits to discharge the output capacitance. When
the ON/OFF pin is set to shutdown level, turns the output transistor off, and turns the discharge shunt function on so
that the output capacitor discharges. These types allow for the VOUT pin reach VSS level rapidly when compared
with the S-1711 Series C/ D/ G/ H types that does not have discharge shunt circuits.
In the S-1711 Series A/ C/ E/ G types, the ON/OFF pin is internally pulled up to VIN or pulled down to VSS, so the
VOUT pin is in the VSS level when in the floating status.
Note with caution that the power consumption of the IC is higher by that to be input to pull-up resistance or pull-down
resistance the power off pin when the S-1711 Series A/ C types operated with the ON/OFF pin connected to VIN
and the S-1711 Series E/ G types with the ON/OFF pin connected to VSS.
