Simple linear power strip

1. Project introduction
(1) Project display
(2) Project introduction
   This project is a linear power board designed for circuit function testing. It has on-board DC12V DC power input interface, Type-C input interface, pin header output interface, and USB female socket output. For the interface, the chip uses CJ7805 linear regulator to stabilize 5V output, and AMS1117 linear regulator to stabilize 3.3V output. An area similar to a perforated board is reserved on the board, with multiple 0603 patch pads and two SOP-16 packages reserved. pad, each voltage output is equipped with an independent switch.
 
2. Work Parameters
Input voltage: +12V
Output voltage: +12V, +5V, +3.3V
Output current: <500mA (Due to the use of a linear regulator, the input and output voltage difference is large, high current output is not recommended)
(1 )+3.3V output voltage
(2)+5V output voltage
(3)+12V output voltage
