THREE–TERMINAL  
POSITIVE FIXED  
VOLTAGE REGULATORS  
This family of fixed voltage regulators are monolithic integrated circuits  
capable of driving loads in excess of 1.0 A. These three–terminal regulators  
employ internal current limiting, thermal shutdown, and safe–area  
compensation. Devices are available with improved specifications, including  
a 2% output voltage tolerance, on A–suffix 5.0, 12 and 15 V device types.  
Although designed primarily as a fixed voltage regulator, these devices  
can be used with external components to obtain adjustable voltages and  
currents. This series of devices can be used with a series–pass transistor to  
boost output current capability at the nominal output voltage.
