1 All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC). Typical values are at TA = +25°C, VIN = 3.6 V.

2 This is the VIN input voltage range over which the rest of the specifications are valid. The part operates as expected until VIN goes below the UVLO threshold.
