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.
1. Low duty pulse techniques are used during test to maintain junction temperature as close to ambient as possible.
2. Quiescent Current is measured where the PNP pass transistor is in saturation. Vin = [VO − 0.5] V guarantees this condition.
3. For 2.5 V version, IQSAT is constrained by the minimum input voltage of 2.5 V.
