    AN2207 power supply

      I'm trying to implement the Application note 2207 to build a milliohmeter. It's my first try on PSOC device and I face a problem.   
      I implement the power supply provided in the AN but when I load the circuit with the PSOC device (CY8C27) the voltage falls to 2.8V instead of 5.5V.   
      I use the LP2950 voltage regulator that is designed up to 100 mA (the AN indicate 55mA consumption), so it seems OK.   
      Do you have any idea to fix my problem? Do you have complete schematics in Orcad format of the AN2207 ?   
      Best regards
