Non-linearity is defined as the deviation of the calculated output-voltage-versus-temperature curve from the best-fit straight line, over the

temperature range specified.

(5)

The LM20 can at most sink 1

μA and source 16 μA.

(6)

Load regulation or output impedance specifications apply over the supply voltage range of 2.4 V to 5.5 V.

(7)

Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output due to heating

effects can be computed by multiplying the internal dissipation by the thermal resistance.

(8)

Line regulation is calculated by subtracting the output voltage at the highest supply input voltage from the output voltage at the lowest

supply input voltage.
