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 LTM8023E is guaranteed to meet performance specifications
from 0°C to 85°C ambient. Specifications over the full –40°C to
85°C ambient operating temperature range are assured by design,
characterization and correlation with statistical process controls. The
LTM8023I is guaranteed to meet specifications over the full –40°C to 85°C
ambient operating temperature range. The LTM8023MP is guaranteed to
meet specifications over the full –55°C to 125°C temperature range. Note
that the maximum internal temperature is determined by specific operating
conditions in conjunction with board layout, the rated package thermal
resistance and other environmental factors.
Note 3: C OUT = 51μF is composed of a 4.7μF ceramic capacitor in parallel
with a 47μF electrolytic.
Note 4: Guaranteed by design.
Note 5: Short circuit current at V IN = 36V is guaranteed by characterization
and correlation. 100% tested at V IN = 10V
