LT3574

3574f

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 LT3574E is guaranteed to meet performance specifications

from 0°C to 125°C junction temperature. Specifications over the –40°C

to 125°C operating junction temperature range are assured by design

characterization and correlation with statistical process controls. The

LT3574I is guaranteed over the full –40°C to 125°C operating junction

temperature range.

Note 3: Current flows out of the RREF pin.

electrical characteristics The
