10 Power Supply Recommendations

The device is designed to operate with a VIN voltage range of 1.1 V to 3.6 V.  The power supply should be well regulated and placed as close to the device terminals as possible. It must be able to withstand all transient and load current steps. In most situations, using the minimum recommended input capacitance of 1 uF is sufficient to prevent the supply voltage from dipping when the switch is turned on.  In cases where the power supply is slow to respond to a large transient current or large load current step, additional bulk capacitance may be required on the input.
