need help with component identification

[antronics]

I have a micromotor that powers up but does not have any output. I isolated the problem down to an IC that looks like an LM 317 regulator, but with 5 pins. No identification marks on the package. Can someone give me some kind of idea what this component could possibly be so I can cross referance it. Any help would be greatly appreciated.

Hi Antronics, By yahoo search "LM 317" I found the following links :

plus many more

AAK,

I guess your links won't be very helpful to antronics.

antronics,

The case looking like a LM317 but having 5 pins might be a T0220-5 case which is used for several types of power ICs like Power Opamps or Mosfet-Drivers, judging from your application it's most likely a Power Opamp as the LM675:

Suggestion: Please, would you provide more info about the application, motor, e.g. voltage, type, etc.
The circuit or chip could also be a motor protector. Visit
