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 1.8 V version VDO is constrained by the minimum input voltage of 2.5 V.
4. For 1.8 V and 2.5 V versions, IQSAT is constrained by the minimum input voltage of 2.5 V.
