Input, Output

An input capacitor is necessary for damping line influences. A resistor of approx. 1

Ω in

C

The TLE 7270 requires a ceramic output capacitor of at least 470 nF to assure stability

of the regulation loop. In order to damp influences resulting from load current surges it is

recommended to add an additional electrolytic capacitor of 4.7

µF to 47 µF at the output

as shown in Figure 3.
