V R is the nominal regulator output voltage. For example: V R = 1.8V, 2.5V, 3.3V, 4.0V, 5.0V.
The input voltage V IN = V R + 1.0V, I OUT = 40 mA.
TCV OUT = (V OUT-HIGH – V OUT-LOW ) *10 6 / (V R * Δ Temperature), V OUT-HIGH = Highest voltage measured
over the temperature range. V OUT-LOW = Lowest voltage measured over the temperature range.
Load regulation is measured at a constant junction temperature using low duty cycle pulse testing.
