Absolute maximum ratings are stress ratings only and functional device operation is not implied. RECOMMENDED OPERATING RATINGS PARAMETER SYMBOL RATINGS UNIT Input Supply Voltage VIN 2.5 ~ 7.0 V Maximum Operating Current (DC) IOPR(MAX) 1.5 A Operating Junction Temperature TJ -40 ~ +125 ℃ Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. ELECTRICAL CHARACTERISTICS (TJ=25°C, VIN =VOUT+1V, IL=10mA, COUT=33µF, unless otherwise specified.)

Dropout voltage specification applies only to output voltages of 2.5V and above. For output voltages below 2.5V, the drop-out voltage is nothing but the input to output differential, since the minimum input voltage is 2.5V. |
