DESCRIPTION  
Note  
The LT1085 voltage regulators are monolithic inte-  
grated circuits designed for use in applications  
requiring a well regulated positive output voltage  
with low input-output differential voltage.  
1) –XX = Voltage Option: 3.3, 5 or 12  
–XX = Left blank for Adjustable Option.  
Features include full power usage of up to 3A load current, internal current limiting and thermal shutdown. Safe area  
protection on the die is also included, providing protection of the series pass Darlington transistor under most conditions.  
The hermetically sealed TO–3 packages are utilised for high reliablitiy and low thermal resistance, whilst the SMD1  
package is designed for surface mount applications.
