threshold
specified
in
most
MOSFET
data
sheets
refers
to
the
minimumvoltage
needed
to
fully
enhance
the
MOSFET. A
lthough
for
the
most
part,
the
MOSFET
will
be
operating
in
the
linear
region
and
the
V
GS
(gate-source
voltage)
will
be
less
than
the
fully
enhanced
V
GS
,
it
is
recommended
the
V
CC
voltage
has
2V
over
the
minimum
V
GS
and
output
voltage
. T
his
is
due
to
the
saturation
voltage
of
the
MIC51

Input Capacitor
G

is
important
for
improved
perfor-
mance
.
Low
ESR
and
low
ES
L
input
capacitors
reduce
both
the
drain
of
the
N

C
hannel
MOSFET
,
as
well
as
the
source
impedance
to
the
MIC51

When
a
load
transient
on
the
output
occurs,
the
load
step
will
also
appear
on
the
input
.
D
eviations
on
the
input
voltage
will
be
reduced
by
the
MIC51

’s
PSRR
,
but
nonetheless
appear
on
the
output
.
T
here
is
no
minimum
input
capacitance,
but
for
optimal
performance
it
is
recommended
that
the
input
capacitance
be
equal
to
or
greater
than
the
output
capacitance
.
Output Capacitor
T
he
MIC51

is
stable
with
any
type
or
value
of
output
capacitor
(even
without
any
output
capacitor!)
. T
his
allows
the
output
capacitor
to
select
which
parameters
of
the
regu-
lator
are
important
. I
n
cases
where
transient
response
is
the
most
important,
low
ESR
and
low
ES
L
ceramic
capacitors
are
recommended
. A
lso,
the
more
capacitance
on
the
output,
the
better
the
transient
response
.
