9 Power Supply Recommendations

The device is designed to operate from an input voltage supply range from 4 V to 40 V. This input supply must be well regulated. If the input supply is located more than a few inches from the TPS7B4250-Q1 device, adding an electrolytic capacitor with a value of 10-µF and a ceramic bypass capacitor at the input is recommended.
