Note

VR is the regulator output voltage setting. For example: VR = 2.5V, 2.7V, 2.85V, 3.0V, 3.3V, 3.6V, 4.0V, 5.0V.

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.

Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value.

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.

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. Please see Section 5.0 “Thermal Considerations” for more details.

Hysteresis voltage is referenced by VR.

Apply for Junction Temperatures of -40°C to +85°C.

The minimum VIN has to justify the conditions = VIN ≥ VR +VDROPOUT and VIN ≥ 2.7V for IL = 0.1 mA to IOUTMAX.
