Conditions
Note 1:
The minimum VIN has to meet two conditions: VIN ≥ 2.7V and VIN ≥ VR + VDROPOUT.
2:
VR is defined as the higher of the two regulator nominal output voltages (VOUT1 or VOUT2).
3:
TCVOUT = ((VOUTmax - VOUTmin) * 106)/(VOUT * T).
4:
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, θJA). Exceeding the maximum allowable power
dissipation causes the device to initiate thermal shutdown
