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 LTM4608A is tested under pulsed load conditions such that

The LTM4608AI is guaranteed over the –40°C to 125°C internal operating
temperature range and the LTM4608AMP is tested and guaranteed over
the full –55°C to 125°C internal operating temperature range. Note that
the maximum ambient temperature consistent with these specifications
is determined by specific operating conditions in conjunction with board
layout, the rated package thermal impedance and other environmental
factors.
