1. Minimum V IN operation after start-up is only limited by the battery’s ability to provide the necessary power as it enters a deeply dis-
charged state.
2. Specification is guaranteed by design and not 100% production tested.
3. I QPWS is measured at V OUT . Multiply this value by V OUT /V IN to get the equivalent input (battery) current.
Note: All limits are guaranteed. The parameters with min and max values are guaranteed with production tests or SQC (Statistical Quality
Control) methods.
