Note 1:

The minimum VIN must meet one condition: VIN  (VR +2.0V).

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.

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.

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.

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.
