*Static-sensitive device. Unused devices must be stored in conductive
material. Protect devices from static discharge and static fields. Stresses
above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. These are stress ratings only and functional
operation of the device at these or any other conditions above those
indicated in the operational sections of the specifications is not implied.
Exposure to Absolute Maximum Rating Conditions for extended periods
may affect device reliability.
ELECTRICAL CHARACTERISTICS: TA = +25°C, unless otherwise specified. (Note1), (Note 2).

(VDR VOUT Inversion)
NOTES: 1. An additional resistor between the VIN pin and the supply voltage may cause alterations in the 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 (comple-
tion of release operation) because of rush current in the delay circuit.
3. VT is the factory-programmed voltage detection threshold.
