9. Refer to ABSOLUTE MAXIMUM RATINGS and APPLICATION INFORMATION for Safe Operating Area.

10.Performance guaranteed over the indicated operating temperature range by design and/or characterization tested at TA [ TJ. Low duty

cycle pulse techniques are used during testing to maintain the junction temperature as close to ambient as possible.

11. Measured when output voltage falls 100 mV below the regulated voltage at Vin = 13.2 V.

12.Values based on design and/or characterization.

13.See APPLICATION INFORMATION section for Reset Thresholds and Reset Delay Time Options
