• 3985-microSMD (3 versions), SOT23-5;     
  • 3480-SOT23-3;     
  • 340L-TO-92, TO-46 metal can

 

 

  • LP3985 - FET    
  • LM3480 - unspecified; since it's a Quasi-LDO, it's probably a single NPN + PNPdriver    
  • LM340L - Darlington NPN (Q10, Q11 in schematic)

 

 

  • 3480, 340L

 

 

  • 3985

 

 

  • 3985-$0.28; 3480-$0.34; 340L-$0.36

 

 

  • 3985-165uA; 3480-4mA; 340L-4.5mA

 

 

  • A 0.01uF capacitor on this pin reduces noise on the regulator output, by removing noise from the internal reference circuit.
