Hysteresis (2)

1. The device is able to properly regulate the output voltage with no load.

2. Guaranteed by design, not tested in production.

3. The current limit is a function of (VIN-VOUT) differential during operation. Maximum available current is limited. Refer to

Section 6.3 Protection features for more information.

Note:

Values in full temperature range are guaranteed by design and/or characterization tested at TA =~ TJ. Low

duty-cycle pulse techniques are used.
