(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)-V OUT1 (*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 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. |
