HIGH RIPPLE-REJECTION LOW DROPOUT MIDDLE OUTPUT CURRENT CMOS VOLTAGE REGULATOR
S-1135 Series
4. Discharge shunt function (S-1135 Series A / B / E / F types)
The S-1135 Series A / B / E / F types have a built-in discharge shunt circuit to discharge the output capacitance.
When the ON / OFF pin is set to power-off 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 the V
than the S-1135 Series C / D / G / H types that does not have a discharge shunt circuit.
