The efficiency of the charge pump regulator varies
Large transient currents flow in the VIN, VOUT, and
with the output voltage version, the applied input
GND traces. To minimize both input and output
voltage, the load current, and the internal operation
ripple, keep the capacitors as close as possible to the
mode of the device.

The approximate efficiency is given by:
A suggested printed circuit board (PCB) routing is
shown in Figure 21. The trace lengths from the input
and output capacitors have been kept as short as
possible.
