10% VR to 90% VR, VIN = 0V to VR +1V,

RL = 25Ω resistive.

VR is the nominal regulator output voltage. For example: VR = 1.8V, 2.5V, 3.3V, 4.0V, 5.0V.

The input voltage VIN = VR + 1.0V, IOUT = 40 mA.

TCVOUT = (VOUT-HIGH – VOUT-LOW) *10

6/(VR * ∆Temperature), VOUT-HIGH is equal to the highest voltage measured

over the temperature range, while VOUT-LOW is equal to the lowest voltage measured over the temperature range.

Load regulation is measured at a constant junction temperature using low duty cycle pulse testing.
