Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Output voltage is measured immediately after turn-on. Changes
Note 4: Line and load regulation are measured on a pulse basis. Output
changes due to die temperature change must be taken into account
separately. Package thermal resistance is 150°C/W.
due to chip warm-up are typically less than 0.005%.
Note 3: Temperature coefficient is measured by dividing the change in
output voltage over the temperature range by the change in temperature.
Note 5: Shunt mode regulation is measured with the input open. With the
input connected, shunt mode current can be reduced to 0mA. Load
regulation will remain the same.
Separate tests are done for hot and cold: T
to 25°C and 25°C to T
.
Note 6: Temperature drift is guaranteed from –25°C to 85°C on LH0070.

Incremental slope is also measured at 25°C. For LT1031BMH, the
5ppm/°C drift specification is for –25°C to 85°C. Drift over the full –55°C
to 125°C range is guaranteed to 7ppm/°C.

Note 8: Guaranteed by design.
