Note:

*1: VOUT(S)=Specified output voltage

*2: VOUT(E)=Effective output voltage

(I.e. the output voltage when "VOUT(S)+1.0V" is provided at the VIN pin while maintaining a certain IOUT value).

*3: VDIF={VIN1(*5) -VOUT1(*4)}

*4: VOUT1=A voltage equal to 98% of the output voltage whenever an amply stabilized IOUT {VOUT(S)+1.0V} is input.

*5: VIN1=The input voltage when VOUT1 appears as input voltage is gradually decreased.

*6: Unless otherwise stated, VIN=VOUT(S) +1.0V

Note:

Stresses greater than those listed under MAXIMUM

RATINGS may cause permanent damage to the

device. This is a stress rating only and functional

operation of the device at these or any other

conditions above those indicated in the operational

sections of this specification is not implied.

Exposure to absolute maximum rating conditions

for extended periods may affect reliability.
