°C/W

(1)

The junction to ambient thermal resistance (

θJA) is specified without a heat sink in still air.

(2)

Changes in output due to self heating can be computed by multiplying the internal dissipation by the thermal resistance.

ACCURACY CHARACTERISTICS

These limits do not include DC load regulation. These stated accuracy limits are with reference to the values in Table 1.

(1)

Limits are specified 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.

ELECTRICAL CHARACTERISTICS

Unless otherwise noted, these specifications apply for +VDD = 2.2 V to 5.5 V. Boldface limits apply for TA = TJ = TMIN to

TMAX ; all other limits TA = TJ = 25°C.

µA

(1)

Typicals are at TJ = TA = 25°C and represent most likely parametric norm.

(2)

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

(3)

Source currents are flowing out of the LMT86/LMT86-Q1. Sink currents are flowing into the LMT86/LMT86-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)

The input current is leakage only and is highest at high temperature. It is typically only 0.001 µA. The 1 µA limit is solely based on a

testing limitation and does not reflect the actual performance of the part.

(6)

Specified by design and characterization.
