Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The LTC1734E is guaranteed to meet performance specifications
from 0 C to 70 C ambient temperature range and 0 C to 100 C junction
temperature range. Specifications over the – 40 C to 85 C operating
ambient temperature range are assured by design, characterization and
correlation with statistical process controls.
Note 3: Assumes that the external PNP pass transistor has negligible B-C
reverse-leakage current when the collector is biased at 4.2V (V
base is biased at 5V (V
