LM145/LM345 Negative Three Amp Regulator
General Description
The LM145 is a three-terminal negative regulator with a
fixed output voltage of
b
5V and up to 3A load current capa-
bility. This device needs only one external componentDa
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.
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.
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
current of the device allows this technique to be used with
good regulation.
The LM145 comes in a hermetic TO-3 package rated at
25W. A reduced temperature range part LM345 is also avail-
able.
