Dimensioning Information on External Components
The input capacitor
Ci
is necessary for compensating line influences. The output capacitor
Co
is necessary
for the stability of the regulating circuit. Stability is guaranteed at values
Ci
≥
10µF,
Co
≥
47µF and an ESR
≤
10Ω within the operating temperature range.

* Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
These are stress ratings only and functional operation of the device at these or any other conditions beyond those
indicated under “recommended operating conditions” is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
