Since both outputs are controlled by the same ENABLE,
the CS8161 is ideal for applications where a sleep mode is
required. Using the CS8161, a section of circuitry such as a
display and nonessential 5V circuits can be shut down
under microprocessor control to conserve energy.
The example in the Applications Diagram shows an auto-
motive radio application where the display is powered by
the 12V on V
OUT1
and the Tuner IC is powered by the 5V
on V
OUT2
. Neither output is required unless both the igni-
tion and the Radio On/Off switch are on.
The output compensation capacitor (Application diagram
C
2
and C
3
) helps determine three main characteristics of a
linear regulator: start-up delay, load transient response
and loop stability.
The capacitor value and type should be based on cost,
availability, size and temperature constraints. A tantalum
or aluminum electrolytic capacitor is best, since a film or
ceramic capacitor with almost zero ESR, can cause insta-
bility. The aluminum electrolytic capacitor is the least
expensive solution, but, if the circuit operates at low tem-
peratures (-25C to -40C), both the value and ESR of the
capacitor will vary considerably. The capacitor manufac-
turers data sheet usually provide this information.
The values for the output capacitors C
2
and C
3
shown in
the Applications Circuit should work for most applica-
tions, however it is not necessarily the best solution.
To determine an acceptable value for C
2
and C
3
for a par-
ticular application, start with tantalum capacitors of the
recommended value on each output and work towards
less expensive alternative parts for each output in turn.
