(1) Limits are specific to TI's AOQL (Average Outgoing Quality Level).
(2) Typicals are at T
J
= T
A
= 25°C and represent most likely parametric norm.
(3) Accuracy is defined as the error between the measured and reference output voltages, tabulated in the Transfer Table at the specified
conditions of supply gain setting, voltage, and temperature (expressed in °C). Accuracy limits include line regulation within the specified
conditions. Accuracy limits do not include load regulation; they assume no DC load.
7.6 Accuracy Characteristics
These limits do not include DC load regulation. These stated accuracy limits are with reference to the values in Table 3.

(3) Source currents are flowing out of the LMT85/LMT85-Q1. Sink currents are flowing into the LMT85/LMT85-Q1.
(4) Line regulation (DC) is calculated by subtracting the output voltage at the highest supply voltage from the output voltage at the lowest
supply voltage. The typical DC line regulation specification does not include the output voltage shift discussed in Output Voltage Shift.
(5) Specified by design and characterization.
