stability. Without them, the regulator outputs will oscillate.
Actual size and type may vary depending upon the
application load and temperature range. Capacitor effective
series resistance (ESR) is also a factor in the IC stability.
Worst−case is determined at the minimum ambient
temperature and maximum load expected.
value above the minimum. One possible purpose of this
would be to maintain the output voltages during brief
conditions of negative input transients that might be
characteristic of a particular system.
expected in the system. To maintain regulator stability down
to −40°C, capacitors rated at that temperature must be used.
