LM4040 Precision Micropower Shunt Voltage Reference

LM4040-5.0
Electrical Characteristics (Extended Temperature Range)
Boldface limits apply for T A =T J =T MIN to T MAX ; all other limits T A =T J = 25˚C. The grades C and D designate initial Reverse
Breakdown Voltage tolerances of ±0.5% and ±1.0%, respectively.
