† Notice: Stresses above those listed under "Absolute Maxi-
mum Ratings" may cause permanent damage to the device.
These are stress ratings only and functional operation of the
device at these or any other conditions above those indicated
in the operation sections of the specifications is not implied.
Exposure to Absolute Maximum Rating conditions for
extended periods may affect device reliability.

Note 1: VR is the regulator output voltage setting.
2: The minimum VIN has to justify the conditions: VIN ≥ VR + VDROPOUT and VIN ≥ 2.7V for IL = 0.1 mA to IOUTMAX
.

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: Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its nominal
value measured at a 1.5V differential.
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 ILMAX at VIN = 6V for T = 10 ms.
7: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction tem-
perature and the thermal resistance from junction-to-air (i.e., TA, TJ, θJA). Exceeding the maximum allowable power dis-
sipation causes the device to initiate thermal shutdown. Please see Section 4.2 “Thermal Considerations” for more
details.
