Notes
a.
b.
c.
The algebraic convention whereby the most negative value is a minimum and the most positive a maximum.
Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
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
for the 3.3-V supply is unity gain. AV
CL
for the 5-V supply is 1.54.
Since the reference uses V
as its supply, its V+ line regulation error is insignificant.
Limits are for all temperature grades unless otherwise noted.
