Note 1:
The minimum VIN must meet one condition: VIN (VR + 2.0V).
2:
VR is the nominal regulator output voltage with an input voltage of VIN = VR + 2.0V. For example: VR = 1.8V, 2.5V, 3.0V, 3.3V, etc.
3:
TCVOUT = (VOUT-HIGH - VOUT-LOW) * 106 / (VR * Temperature), VOUT-HIGH = highest voltage measured over the temperature range. VOUT-LOW = lowest voltage measured over the temperature range.
4:
Load regulation is measured at a constant junction temperature using low duty cycle pulse testing. Changes in output voltage due to heating effects are determined using thermal regulation specification TCVOUT.
5:
Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its measured value with an applied input voltage of VR + 2.0V.
