I/O Filtering and Noise Reduction
All models in the LSM D12 Series are tested and specifi ed with external 22μF
tantalum input and output capacitors. These capacitors are necessary to
accommodate our test equipment and may not be required to achieve desired
performance in your application. The LSM D12'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.
are fully rated to handle the units’ input ripple currents. Similarly, the internal
output capacitors are specifi ed for low ESR and full-range frequency response.
As shown in the Performance Curves, removal of the external 22μF tantalum
output caps has minimal effect on output noise.
fi ltering techniques, the simplest being the installation of external I/O caps.
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 appropri-
ate 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 imped-
ances can greatly affect system stability. Your specifi c system confi guration
may necessitate additional considerations.

specifi ed performance in your applications. All models are stable and regulate within spec under
