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

affect device reliability.

Note 1: VR is the regulator output voltage setting. For example: VR = 1.8V, 2.5V, 2.7V, 2.85V, 3.0V, 3.3V, 3.6V,
4.0V, 5.0V.
2: TC VOUT = (VOUTMAX – VOUTMIN)x 106
VOUT x T
3: Regulation is measured at a constant junction temperature using low-duty-cycle pulse testing. Load regu-
lation 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.
4: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its
nominal value.
5: Thermal Regulation is defined as the change in output voltage at a time T after a change in power dissipa-
tion is applied, excluding load or line regulation effects. Specifications are for a current pulse equal to ILMAX
at VIN = 6V for T = 10 ms.
6: 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. See Section 5.0
“Thermal Considerations” for more details.
7: Hysteresis voltage is referenced by VR.
8: The minimum VIN has to justify the conditions: VIN  VR + VDROPOUT and VIN  2.7V for IL = 0.1 mA to
IOUTMAX.
9: Apply for junction temperatures of -40°C to +85°C.
