11 Power Supply Recommendations

The device is designed to operate with a VIN range of 1.1 V to 3.6 V. This supply must be well regulated and

placed as close to the device terminal as possible with the recommended 1-

μF bypass capacitor. 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.

12 Layout

12.1 Layout Guidelines

For best performance, all traces should be as short as possible. To be most effective, the input and output

capacitors should be placed close to the device to minimize the effects that parasitic trace inductances may have

on normal and short-circuit operation. Using wide traces for VIN, VOUT, and GND will help minimize the parasitic

electrical effects along with minimizing the case to ambient thermal impedance.
