Application information
Input and output capacitors
Input and output capacitors improve the performance of the device; the actual capacitance
should be optimized for the particular application. For all applications, a 0.1 µF or greater
ceramic bypass capacitor between IN and GND as close to the device as possible is
recommended for local noise decoupling. This precaution also reduces ringing on the input
due to power supply transients.
An additional capacitor may be needed on the input to reduce input voltage overshoots from
exceeding the absolute maximum voltage of the device during heavy transient conditions.
This is especially important during bench testing when long, inductive cables are used to
connect the evaluation board to the bench power supply. The value of 100 µF may be
adequate in most situations.
An output capacitor is not required for device functionality, but placing a high-value (in the
order of 10 - 100 µF) electrolytic capacitor on the output pins is recommended when large
transient currents are expected on the output.
