Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Conditions are  
conditions under which the device functions but the specifications might not be guaranteed. For guaranteed specifications  
and test conditions see the Electrical Characteristics.  
Note2:  
The maximum power dissipation is a function of the maximum junction temperature, TJmax ; total thermal resistance, θJA,  
and ambient temperature TA. The maximum allowable power dissipation at any ambient temperature is Tjmax-TA / θJA. If  
this dissipation is exceeded, the die temperature will rise above 150°C and IC will go into thermal shutdown.  
Note3: Low duty pulse techniques are used during test to maintain junction temperature as close to ambient as possible.  
Note4: The type of output capacitor should be tantalum or aluminum.  
Definitions  
Dropout Voltage  
Load Regulation  
The input/output Voltage differential at which the  
regulator output no longer maintains regulation against  
further reductions in input voltage. Measured when the  
output drops 2% below its nominal value. Dropout  
voltage is affected by junction temperature, load cur-  
rent and minimum input supply requirements.  
The change in output voltage for a change in load  
current at constant chip temperature. The measure-  
ment is made under conditions of low dissipation or by  
using pulse techniques such that average chip tem-  
perature is not significantly affected.  
Maximum Power Dissipation  
Line Regulation  
The maximum total device dissipation for which the  
regulator will operate within specifications.  
The change in output voltage for a change in input volt-  
age. The measurement is made under conditions of low  
dissipation or by using pulse techniques such that av-  
erage chip temperature is not significantly affected.  
Quiescent Bias Current  
Current which is used to operate the regulator chip  
and is not delivered to the load.
