What are the power requirements of the Wi-Fi module?

Note that the output voltage ripple of 3.3V is less than 100mV, and the DC/DC has the ability to output the current 200mA. And when the output current is 450mA under the dynamic conditions, the output voltage drop does not exceed 2.8V. The LDO supplies power to the Wi-Fi module. If you use LDO, you need to use a chip with a power supply current of more than 500mA, and pay attention to the heat dissipation. It is recommended to use a switching power supply chip when the input voltage is higher than 5V.
