Conditions

Note 1:

VR is the nominal regulator output voltage.

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.

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). See Section

“Temperature Specifications” for more information. Exceeding the maximum allowable power

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.

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

below its nominal value that was measured with an input voltage of VIN =VR +1.2V.

PSRR measurement is carried out with CIN =0 µF, VIN =7V, IOUT =50mA, VINAC =0.4Vpkpk

Not production tested.
