Output Capacitor Selection
capacitors for Cout and C
The value of the output capacitor should be 1uF or higher. Either ceramic chip or a
tantalum capacitor may be used at the output. Use of ceramic chip capacitors offer
significant advantages over tantalum capacitors. A Ceramic capacitor is typically cheaper
than a tantalum capacitor, it usually has a smaller footprint, lower height, and lighter
weight than a tantalum capacitor. Furthermore, unlike tantalum capacitors which are
polarized and can be damaged if connected incorrectly, ceramic capacitors are non-
polarized. Low value ceramic chip capacitors with X5R or X7R dielectric are available in the
100pF to 4.7uF range. Beware of using ceramic capacitors with Y5V dielectric since their
ESR increases significantly at cold temperatures. Figure 9 shows a list of recommended
ceramic capacitors for use at the output of S52xxM.
ESR tantalum capacitor with maximum rated ESR at or below 0.4Ω. Low ESR tantalum
capacitors, such as the TPS series from AVX Corporation (www.avxcorp.com) or the T495
series from Kemet (www.kemet.com) may be used.
low ESR output capacitor for superior load transient response. The S52xxM is stable with
no load.
