Note 1: The minimum V_IN must meet one condition: V_IN ≥ (V_R + 2.0V).
2: V_R is the nominal regulator output voltage with an input voltage of V_IN = V_R + 2.0V.
For example: V_R = 1.8V, 2.5V, 3.0V, 3.3V, etc.
3: TCV_OUT = (V_OUT-HIGH - V_OUT-LOW) *10⁶ / (V_R * ΔTemperature), V_OUT-HIGH = highest voltage measured
over the temperature range. V_OUT-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
TCV_OUT.
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 V_R + 2.0V.
