9 Power Supply Recommendations

The device is designed to operate with an input voltage supply from 4 V to 40 V. This input supply must be well regulated. If the input supply is more than a few inches away from the TPS7B4254-Q1 device, TI recommends adding an electrolytic capacitor with a value of 10 μF and a ceramic bypass capacitor at the input.
