The TPS3899 is designed to operate from an input supply with a voltage range between 0.85V and 6V. An input supply capacitor is not required for this device; however, if the input supply is noisy, then good analog practice is to place a 0.1µF capacitor between the VDD pin and the GND pin. Also, placing a 10nF to 100nF capacitor between the SENSE pin and GND can reduce the sensitivity to transient voltages on the monitored signal. This device has a 6.5V absolute maximum rating on the VDD pin. If the voltage supply providing power to VDD is susceptible to any large voltage transient that can exceed 6.5V, additional precautions must be taken.
