NOTES

1All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC) methods.

2Dynamic supply current is higher due to the gate charge being delivered at the switching frequency.

*TJ is calculated from the ambient temperature, TA, and power dissipation, PD,

according to the following formulas: ADP1147AN-3.3, ADP1147AN-5: TJ = TA +

(PD

× 110°C/W). ADP1147AR-3.3, ADP1147AR-5: T

J = TA+(PD
