1: 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.
2: TCVOUT = (VOUT-HIGH – VOUT-LOW) *106 / (VR * ΔTemperature), VOUT-HIGH = Highest voltage measured
over the temperature range. VOUT-LOW = Lowest voltage measured over the temperature range.
3: Load regulation is measured at a constant junction temperature using low duty cycle pulse testing.
