Add in Q4 it goes up to 107mA @ 5V
Add in Q5 it goes up to 130mA
I think it must be close to the limit of the voltage regulator which is only rated at 100mA

I am running 4 x QRD1114 sensors (not using the middle one) and 2 x GP2D12 sensors on one now so I would imagine I am well over.. I have some T0-220 package regulators kicking around so could swap to one of those if need be..
Re the QRD1114 sensors, you are correct they are a short range sensor intended to "fill" the blind spot in the GP2D12 / GP2D120 sensor's range.
