LT1031/LH0070
1031fb
(LH0070) The
● denotes the specifications which apply over the full
operating temperature range. VIN = 15V, RL = 10k, –55°C ≤ TA ≤ 125°C, unless noted.
ELECTRICAL CHARACTERISTICS
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
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.
Separate tests are done for hot and cold: TMIN to 25°C and 25°C to TMAX.
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 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.
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.
Note 6: Temperature drift is guaranteed from –25
°C to 85°C on LH0070.
Note 7: See curve for guaranteed minimum VIN versus IOUT.
Note 8: Guaranteed by design.
