FEATURES  
DESCRIPTION  
This series of fixed-voltage integrated-circuit voltage

regulators is designed for wide range of

No External Components  
applications. These applications include on-card  
regulation for elimination of noise and distribution  
problems associated with single-point regulation. In  
addition, they can be used with power-pass elements  
to make high-current voltage regulators. One of these  
regulators can deliver up to 100 mA of output current.  
The internal limiting and thermal-shutdown features of  
these regulators essentially make them immune to  
overload. When used as a replacement for a Zener  
diode-resistor combination, an effective improvement  
in output impedance can be obtained, together with  
lower bias current.  
Internal Thermal-Overload Protection  
Internal Short-Circuit Current Limiting  
The μA78L00C and μA78L00AC series devices are  
characterized for operation over the virtual junction  
temperature range of 0°C to 125°C. The μA78L05AI  
device is characterized for operation over the virtual  
junction temperature range of −40°C to 125°C.
