I/O Filtering and Noise Reduction
All models in the LSN2 Series are tested and specifi ed with external 1 || 10μF
ceramic/tantalum output capacitors and a 22μF tantalum input capacitor.
These capacitors are necessary to accommodate our test equipment and
may not be required to achieve desired performance in your application. The
LSN2's are designed with high-quality, high-performance internal I/O caps,
and will operate within spec in most applications with no additional external
components.
fully rated to handle the units' input ripple currents. Similarly, the internal out-
put capacitors are specifi ed for low ESR and full-range frequency response.
In particular, the LSN2's input capacitors are specifi ed for low ESR and are

minimize high-frequency variations in input voltage (usually caused by IR
drops in conductors leading to the DC/DC) as the switching converter draws
pulses of current. Input capacitors should be selected for bulk capacitance
(at appropriate frequencies), low ESR, and high rms-ripple-current ratings.
The switching nature of modern DC/DCs requires that the dc input voltage
source have low ac impedance at the frequencies of interest. Highly inductive
source impedances can greatly affect system stability. Your specifi c system
confi guration may necessitate additional considerations.
In critical applications, input/output ripple/noise may be further reduced using
External input capacitors serve primarily as energy-storage devices. They
