Hi. 

Customer's device didn't work well at low temperatures ( -30 C ) and  they found  that problem were with ADR01BRZ.

Tested stand along IC at -30C temperature loaded on 1.1k resistor  (9.1 mA) with input voltage 15 V, output was 9.990 to 9.991 V.

initial accuracy is 9.995 -10.005 V, temperature drift 3ppm/C, delta 55C will cause  -1.65 mV drift.

Worst case must be 9.995-0.00165 = 9.993 V.

Any idea ? what else could affect ?
