Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The LTC4412E is guaranteed to meet performance specifications
from 0°C to 85°C operating temperature range. Specifications over the –
40°C to 85°C operating temperature range are assured by design,
characterization and correlation with statistical process controls. The
LTC4412IS6 is guaranteed over the – 40°C to 85°C operating temperature
range.
Note 3: This results in the same supply current as would be observed with
an external P-channel MOSFET connected to the LTC4412 and operating in
forward regulation.
ELECTRICAL CHARACTERISTICS
