TEST AND APPLICATION CIRCUIT

The output capacitor is required for stability. Though

the 100

µF shown is the minimum recommended

value, actual size and type may vary depending

upon the application load and temperature range.

Capacitor effectiveseries resistance (ESR) also fac-

tors in the IC stability. Since ESR varies from one

brand to the next,some bench work may be required

to determine the minimum capacitor value to use in

production. Worst-case is usually determined at the

minimum ambient temperature and maximum load

expected.

Output capacitors can be increased in size to any

desired value above the minimum. One possible

purpose of this would be to maintain the output vol-

tages during brief conditions of negative input tran-

sients that might be characteristics of a particular

system.

Capacitors must also be rated at all ambient tempe-

rature expected in the system. Many aluminum type

electrolytics will freeze at temperatures less than –

30

°C, reducing their effective capacitance to zero.

To maintain regulator stability down to – 40

°C, ca-

pacitors rated at that temperature (such as tan-

talums) must be used.
