VOUT(S): Specified output voltage
*3. The output current at which the output voltage becomes 97 % of VOUT(E) after gradually increasing the
output current.
*4. Design assurance
*5. The ideal efficiency is indicated by the following expression.
Efficiency (
η)=(VOUT × IOUT) / (2.0 × VIN × IOUT)
*6. In case of VOUT ≤ 2.9 V, VIN=1.6 V
