_______________________________________________________________________________________
Note 1:
Output current is further limited by maximum allowable package power dissipation.
Note 2:
Because the reference uses VL as its supply, the REF line regulation error is insignificant.
Note 3:
The main switching outputs track the reference voltage. Loading the reference reduces the main outputs slightly according
to the closed-loop gain (AV
CL
) and the reference voltage load regulation error. AV
CL
for the +3.3V supply is unity gain.
AV
CL
for the +5V supply is 1.54.
