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 condi-
tions above those indicated in the operational sec-
tions of this specification is not implied. Exposure
to absolute maximum rating conditions for extended
periods may affect reliability.

Note: *1: V_OUT(S)=Specified output voltage.
*2: V_OUT(E)=Effective output voltage.
(I.e. the output voltage when "V_OUT(S)+1.0V" is provided at the VIN pin while maintaining a certain I_OUT value).
*3: Vdif={V_IN1(*5)-V_OUT1(*4)}.
*4: V_OUT1=A voltage equal to 98% of the output voltage whenever an amply stabilized I_OUT {V_OUT(S) + 1.0V} is input.
*5: V_IN1=The input voltage when V_OUT1 appears as input voltage is gradually decreased.
*6: Unless otherwise stated, V_IN=V_OUT(S)+1.0V
