I can't figure whats wrong.
I connect 2 18650 batteries (8.4V) up to the circuit.
I have 1kΩ from Output to Adjust and 3kΩ from Adjust to ground.
The output pin should have 5 volts. but I measure 5.5 volts
I tried putting 3MΩ and 1MΩ in place of the resistors and the voltage is 7.5 out
also tried 2k and 1 k to get calculated voltage out of 3.75 and i get 4.4 out??
also the resistance from ouitput to ground seems to affect the output voltage...

(could I have wrong pinout?)
