Note
1:
An additional resistor between the VIN pin and the supply voltage may alter the electrical characteristics due to the increasing values of
VDR.
2:
The power consumption during power-start to output being stable (release operation) is 2
A greater than it is after that period
(completion of release operation) because of rush current in the delay circuit.
3:
VT is the factory-programmed voltage detection threshold.
