From the project
USB-C PCB module with 250 mA LDO
The LDO 250 is the first board in the modular EGG design series. The EGG series is a conceptual compilation of many different modules. Modules are created from independent circuit parts which have repeatedly appeared in my PCB designs. Each of my circuits starts with the voltage source which is why LDO 250 provides a linear voltage regulator with a low dropout voltage and a maximum current of 250 mA.
