Hi all,
my LT3093 LDO is configured for an output voltage of -0.24V (derived from an input voltage of -2.3V). Where should I connect the PGFB pin? To IN or to OUT?
The datasheet states:
"Please note that programmable power good and fast start-up capabilities are disabled for output voltages between 0V and –300mV."
and
Page 15: "If power good and fast start-up functionality are not needed, tie PGFB to IN."
Page 22: "If fast start-up capability is not used, tie PGFB to IN or to OUT (for output voltages more than –300mV)."
Is there any advantage connecting PGFB to OUT instead of IN?
Thank you!
