__________Applications Information
Capacitor Selection
Charge-Pump Capacitors C1 and C2
The values of charge-pump capacitors C1 and C2 are
critical to ensure adequate output current and avoid
excessive peak currents. Use values in the range of
0.22 μ F to 1.0 μ F. Larger capacitors (up to 50 μ F) can
be used, but larger capacitors will increase output rip-
ple. Ceramic or tantalum capacitors are recommend-
ed.
Input and Output Capacitors, C3 and C4
The type of input bypass capacitor (C3) and output fil-
When using ceramic capacitors, the values of C3 and
C4 can be reduced to 2 μ F and 1 μ F, respectively. If the
input supply source impedance is very low, C3 may not
be necessary.
Many capacitors exhibit 40% to 50% variation over
temperature. Compensate for capacitor temperature
coefficient by selecting a larger nominal value to
ensure proper operation over temperature. Table 1 lists
capacitor suppliers.
ter capacitor (C4) used is not critical, but it does affect
performance. Tantalums, ceramics, or aluminum elec-
trolytics are suggested. For smallest size, use Sprague
595D106X0010A2 surface-mount capacitors, which
measure 3.7mm x 1.8mm (0.146in x 0.072in). For low-

est ripple, use large, low effective-series-resistance
(ESR) ceramic or tantalum capacitors. For lowest cost,
use aluminum electrolytic or tantalum capacitors.
Figure 2 shows the component values for proper oper-
ation using minimal board space. The input bypass
capacitor (C3) and output filter capacitor (C4) should
both be at least 10 μ F when using aluminum electrolyt-
