LM145/LM345 Negative Three Amp Regulator  
General Description  
The LM145 is a three-terminal negative regulator with a  
current of the device allows this technique to be used with  
good regulation.  
b
fixed output voltage of 5V and up to 3A load current capa-  
bility. This device needs only one external componentÐa  
compensation capacitor at the output, making it easy to ap-  
ply. Worst case guarantees on output voltage deviation due  
to any combination of line, load or temperature variation  
assure satisfactory system operation.  
The LM145 comes in a hermetic TO-3 package rated at  
25W. A reduced temperature range part LM345 is also avail-  
able.  
Features  
Y
Exceptional effort has been made to make the LM145 im-  
mune to overload conditions. The regulator has current lim-  
iting which is independent of temperature, combined with  
thermal overload protection. Internal current limiting pro-  
tects against momentary faults while thermal shutdown pre-  
vents junction temperatures from exceeding safe limits dur-  
ing prolonged overloads.

Output voltage accurate to better than 2%

Current limit constant with temperature  
Internal thermal shutdown protection  
Operates with input-output voltage differential of 2.8V at  
full rated load over full temperature range  
Regulation guaranteed with 25W power dissipation  
3A output current guaranteed

Although primarily intended for fixed output voltage applica-  
tions, the LM145 may be programmed for higher output volt-  
ages with a simple resistive divider. The low quiescent drain
