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 5.0 V circuits can be shut down
under microprocessor control to conserve energy.

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
instability. The aluminum electrolytic capacitor is the
cheapest solution, but, if the circuit operates at low
temperatures (−25°C to −40°C), both the value and ESR of
the capacitor will vary considerably. The capacitor
manufacturers data sheet usually provides this information.
