Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product

performance may not be indicated by the Electrical Characteristics if operated under different conditions.

4. LM1117: Tlow = 0°C ,

Thigh = 125°C

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

6. The regulator output current must not exceed 1.0 A with Vin greater than 12 V.
