APPLICATIONS INFORMATION
For the step-up converter, a tantalum capacitor may be used
in demanding applications that have large load transients.
Another method of improving the transient response is to
add a small feedforward capacitor across the top resistor
of the feedback divider (from V
OUTB
 to FBB). A typical value
of 22pF will generally suf ce.
Ceramic capacitors are also a good choice for input de-
coupling of the step-up converter and should be located
as close as possible to the device. A 2.2糉 input capacitor
is suf cient for most applications, although larger values
may be used without limitations. The LDO regulator will
have improved performance with an input capacitor, but
it is not required. Table 2 shows a list of several ceramic
capacitor manufacturers. Consult the manufacturers di-
rectly for detailed information on their selection of ceramic
capacitors.
