2. In the E type, the minimum operating voltage becomes 2.0 V as V
3. Also, in the E type, when sharply increasing only VIN pin voltage at 1 ms/V or less,
in V
capacitor when load current or the voltage regulator is powered on at the time of
release, set V
with the SENSE pin fixed to −V
output pin of voltage detector. Be careful. In this case, this release pulse is removed
by setting the time constant of VOR pin 20 ms or more with capacitance and pull-up
resistance. In addition, when the voltage of SENSE pin is fixed to between the
detection voltage and the release voltage at the detect condition, if sharply increasing
only VIN pin voltage at 1 ms/V or less, the output of the detector turns to the release
condition. If this action is a problem in your system, please connect SENSE pin to
VIN pin.
