Table 2. Surface-Mount Inductor
Specifications
A 47µF, 10V surface-mount tantalum (SMT) output filter
capacitor provides 80mV output ripple when stepping
up from 2V to 5V. Smaller capacitors (down to 10µF
with higher ESRs) are acceptable for light loads or in
applications that can tolerate higher output ripple.
Values in the 10µF to 100µF range are recommended.
The equivalent series resistance (ESR) of both bypass
and filter capacitors affects efficiency and output rip-
ple. Output voltage ripple is the product of the peak

inductor current and the output capacitor ESR. Use
low-ESR capacitors for best performance, or connect
two or more filter capacitors in parallel. Low-ESR, SMT
tantalum capacitors are currently available from
Sprague (595D series) AVX (TPS series) and other
sources. Ceramic surface-mount and Sanyo OS-CON
organic-semiconductor through-hole capacitors also
exhibit very low ESR, and are especially useful for oper-
ation at cold temperatures. See
gested component suppliers.
