Conditions

Note 1:

2:

Load regulation is measured at a constant ambient temperature using a DC current source. Load

regulation is tested over a load range 1 mA to the maximum specified output current.

3:

The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable

dissipation will cause the device operating junction temperature to exceed the maximum +150°C rating.

Sustained junction temperatures above +150°C might impact the device reliability.

4:

Dropout voltage is defined as the input-to-output voltage differential at which the output voltage drops 2%

5:

6:

Not production tested.
