3.3.2 Power reference circuit
In actual design, the power supply can be designed using a switched DC power supply or a
linear LDO power supply, and then use the PMOS tube to control the power supply input so
that the power supply can be completely cut off. Both design circuits need to provide
sufficient current. Specific reference to the following circuit design
