The change of output voltage over the operating temperature The change of output voltage after the device is cycled through change and normalized by the output voltage at 25°C, expressed temperatures from +25°C to −40°C to +85°C and back to +25°C. in ppm/°C. The equation follows This is a typical value from a sample of parts put through such a cycle TCV [ V T −V T V = ° − _ V (25 C) O ppm/ C ° ] ( ) ( ) O 2 O 1 6 = × V V ( °C)×(T −T ) 10 O HYS O O _TC O 25 2 1 V ° O C − where: V [ V O HYS ppm] (25 ) O_TC 6 = × _ 10 V V ( O 25°C) O (25°C) = VO at 25°C. VO (T1) = VO at Temperature 1. where: VO (T2) = VO at Temperature 2. VO (25°C) = VO at 25°C.

specified temperature range. The change in output voltage due to a specified change in load current. It includes the effects of self-heating. Load regulation is expressed in either microvolts per milliampere, parts per million per milliampere, or ohms of dc output resistance.
Long-Term Stability (ΔVO)
Typical shift of output voltage at 25°C on a sample of parts subjected to an operation life test of 1000 hours at 125°C.
