The minimum VIN has to meet two conditions: VIN  2.7V and VIN  VR + VDROPOUT.
VR is defined as the higher of the two regulator nominal output voltages (VOUT1 or VOUT2).
TCVOUT = ((VOUTmax - VOUTmin) * 106)/(VOUT * T).
Regulation is measured at a constant junction temperature using low duty-cycle pulse testing. Load regulation is tested
over a load range from 0.1 mA to the maximum specified output current. Changes in output voltage due to heating
effects are covered by the thermal regulation specification.
5: Thermal regulation is defined as the change in output voltage at a time t after a change in power dissipation is applied,
excluding load or line regulation effects. Specifications are for a current pulse equal to ILMAX at VIN = 6V for t = 10 msec.
6: Dropout voltage is defined as the input-to-output voltage differential at which the output voltage drops 2% below its
value measured at a 1V differential.
7: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction
temperature and the thermal resistance from junction to air (i.e., TA, TJ, JA). Exceeding the maximum allowable power
dissipation causes the device to initiate thermal shutdown.
