Limits are specific to TI's AOQL (Average Outgoing Quality Level).

(2)

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.

Source currents are flowing out of the LMT87 and LMT87-Q1. Sink currents are flowing into the LMT87 and LMT87-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.
