Thermal effects must be taken into account separately. ‡ Input voltage regulation is expressed here as the percentage change in output voltage per 1-V change at the input. NOTE 3: Due to the dropout voltage and output current-limiting characteristics of this device, output current is limited to less than 700 mA at input-to-output voltage differentials of less than 25 V. |
