In
Table
1-1
(and
paragraph
5-20),
change
the
INTERNAL
IMPEDANCE
AS
A
CONSTANT
VOLTAGE
SOURCE
(Output
Impedance)
specification
to
read:
"OUTPl1l'
IMPEDANCE
{TYPICAL):
Approximated
by
a 5 milliohm resistance in
series
with a 1 microhenry inductance.
On
page
3-2, Figure 3-4, disconnect
strap
between
terminals
A4
and
A5.
and
connect
A5
to
+S.
On
page
3-3, Figure 3-6, disconnect
strap
between
terminals
A7
and
AS
and
con-
nect
A8

Add
the following note
to
paragraph
3-18
on
page
3-2
and
to
paragraph
4-41
on
page
4-7:
"A
protection
circuit
which
protects the
series
regulator
from
overload
damage
is
ac-
tivated whenever: (1)
a.
short
is
placed
across the supply, or (2) the output
is
rapidly
down
progranmed
by
an
increment
of
more
than 4
to
10
volts.
When
activated,
the protection
circuit
limits
the supply's
output current to about
101
of
rating for a
period of
from
0.5
to
10
seconds depending
on
the
model
and
the load conditions."
On
page
5-6, paragraph 5-22,
change
steps a
and
f as follows:
a.
Connect
test
setup
shown
in Figure 5-4
with switch
51
closed.
f.
Insert
load
resistor
(Ry)
by
opening
switch
S1.
Also,
add
the following note:
"The
short
circuit
protection
circuit
in
this
supply
will
be
activated
if
switch
: S 1
is
closed instead of
opened
during
·
this
test."
On
page
5-8,
in
Step 3 of Table 5-4,
change
the
