%VIN VIN = 2.5V to 6.0V
Note 1: The minimum VIN has to meet two conditions: VIN = 2.7V and VIN = VR + VDROPOUT.
2: VR is the regulator output voltage setting. For example: VR = 1.8V, 2.7V, 2.8V, 2.85V, 3.0V, 3.3V.

VOUT × ΔT
4: Regulation is measured at a constant junction temperature using low duty cycle pulse testing. Load regulation is tested
over a load range from 1.0 mA to the maximum specified output current. Changes in output voltage due to heating
effects are covered by the Thermal Regulation specification.
5: Dropout Voltage is defined as the input-to-output differential at which the output voltage drops 2% below its nominal
value.
6: 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 IMAX at VIN = 6V for T = 10 ms.
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).
8: Time required for VOUT to reach 95% of VR (output voltage setting), after VSHDN is switched from 0 to VIN.
