What is the function of LDO (Low Dropout Regulator) in the NuMicro? Family? Can LDO output be used to drive other extern

[a_ziliu]

The LDO mainly provides a stable operating voltage of 1.8V for use in internal circuit of a chip, including RC oscillator, SRAM, and Flash.
In consideration of chip operational stability, it is not recommended that LDO output be used to drive other external chips.
