I fed the _output_ of the LDO03 with 1.2 Volt. As this output supplies
VCCINT, that meant that I applied VCCINT. However I don't know exactly, what
an LDO03 does with the output siupplied with voltage but the input not
supplied.

90 mA on an external 1.2V supply, feeding the _output_ of the regulator
