The reference output will both source and sink up to 10mA and can be used as ae shunt regulator (two terminal zener) with the same precision characteristics as the three terminal connection. Special care has been taken to minimize thermal regulation effects and temperature induced hysteresis. The reference is based on a buried zener diode structure which eliminates noise and stability problems associated with surface breakdown devices. Further, a subsurface zener exhibits better temperature drift and time stability than aven the best band-gap references. Unigue circu design makes the LT1031M/683 the first three terminal IC reference to offer ultra low drift without the use of high power on-chip heaters. Output voltage is pre-trimmed to 0.05% accuracy. Tne LT1031M/883 can be used as a plug-replacement for the AD581 and LH0070, with improved electrical and ther- mal performance. The device is processed to the requirements of MIL-STD- 863 Class B to yield circuits usable in precision military applications.

See PDA Test Notes. @ Note A: Output voltage is measured immediately after turn-on. Changes due to chip warm-up are typically less than 0.005%. Note 8: 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; Tin to 25C, and 25C to Tmax. Incremental slope is also measured at 25. For L11031BMH, the SppnuC to +125C range is guaranteed to 7ppmC. Note C: 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 resis- tance is 150C/W.

The PDA is specified as 5% based on failures from group A, subgroup 1, tests after cooldown as the final electrical test in accordance with method 5004 of MIL-STD-983 Class 6. Tha verified failuras of group A, subgroup 1, after burn-in divided by the total number of devices submitted for burn-in in that lat shall be used to determina the percant for the jot. Linear Technology Corporation reserves the right to test to tighter limits than those given. Note D: Shunt mode reguiation is measured with the input open. With the input connected, shunt mode currant can be reduced to OmA. Load regulation will remain the same. Note E: Temperature drift is guaranteed from -25C to +85C on LH0070. Note F: See curve on standard data sheet for guaranteed minimum Vin versus lout. Nota G: Guaranteed by design. 1D. No. 06-10-0037 Rev.
