*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.

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