I noticed that in the app note slyy151a (LDO basics), page 11, eqn. 1, Iq is used for power dissipation consumed and Iground (page 8, eqn1) is used for Pd in the thermal power dissipation calculation. Iq = 8mA and Iground = 16mA, so the difference between the two is large. Why are different currents used for these two calculations? Why are these currents so large? The commercial parts use a lot less current, on the order of a 100uA.
