10 Power Supply Recommendations
The device is designed to operate with an input voltage range of 2.5 V to 16 V. This supply must be well
regulated and placed as close to the device terminals as possible. It must also be able to withstand all transient
and load currents, using a recommended input capacitance of 1 µF if necessary. If the supply is located more
than a few inches from the device terminals, additional bulk capacitance may be required in addition to the
ceramic bypass capacitors. If additional bulk capacitance is required, an electrolytic, tantalum, or ceramic
capacitor of 10 µF may be sufficient.

11.1 Layout Guidelines
For best performance, VIN, VOUT, and GND traces must be as short and wide as possible to help minimize the
parasitic electrical effects. To be most effective, the input and output capacitors must be placed close to the
device to minimize the effects that parasitic trace inductances may have on normal operation.
