The equation follows: where: TCVO[ppm /°C ] = VO(T2 ) − VO(T1) VO(25°C) × (T2 − T1) × 106 VO(25ЊC) = VO at 25ЊC VO(T1) = VO at temperature 1 VO(T2) = VO at temperature 2 Line Regulation (∆VO/∆VIN) The change in output voltage due to a specified change in input voltage. It includes the effects of self-heating. Line regulation is expressed in either percent per volt, parts per million per volt, or microvolts per volt change in input voltage. Load Regulation (∆VO/∆ILOAD) 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 Ω of dc output resistance. Long-Term Stability (∆VO) Typical shift of output voltage at 25ЊC on a sample of parts subjected to an operation life test of 1000 hours at 125ЊC: where: ∆VO = (VO t0 ) − VO(t1) ∆VO[ppm] = VO(t0 ) − VO(t1) VO(t0 ) × 106 VO(t0) = VO at 25ЊC at time 0 VO(t1) = VO at 25ЊC after 1000 hours operation at 125ЊC Thermal Hysteresis (VO_HYS) The change of output voltage after the device is cycled through temperatures from +25ЊC to –40ЊC to +85°C and back to +25ЊC. This is a typical value from a sample of parts put through such a cycle: where: ( ) VO_HYS = VO 25°C − VO_TC [ ] VO_HYS ppm = VO(25°C) − VO_TC VO(25°C) × 106 VO(25ЊC) = VO at 25ЊC VO_TC = VO at 25ЊC after temperature cycle at +25ЊC to –40ЊC to +85ЊC and back to +25ЊC Operating Temperature The temperature extremes at which the device can still function. Parts may deviate from their specified performance outside the specified temperature range. REV. D –7–
