Actually you're right Flip. I was quickly looking at MCP1702 specs and saw it using a pass FEt in lieu of more traditional transistor array for the device. I was thinking hey this will have less V drop across it.

When in fact its exactly the same as a traditional device P = (Vin -Vout) x Iout. Reading the TI tech paper on this, SBVA027, details lots of info on the SOA of these devices.

I have to now go back and look at the current thru the regulator. No use chasing tails if it's in the SOA of operations.
