NOTES
1 All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC).
2 For higher efficiency operation, tie the DRV pin to the output for IL < 250 mA, and VIN > 3 V.
3 V(IN) - V(SW), includes voltage drop across internal current sensor.
Specifications subject to change without notice.
