Input, Output
An input capacitor is necessary for damping line influences. A resistor of approx. 1 Ω in
series with
In contrast to most low drop voltage regulators the TLE 7274 only needs moderate
capacitance at the output to assure stability of the regulation loop. This offers more
design flexibility to the circuit designer providing for cost efficient solutions.
The TLE 7274 requires a ceramic output capacitor of at least 470 nF. 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
