Does the LDO (Low Dropout Regulator) in the NuMicro? Family need to connect to an external capacitor?

To stabilize the LDO output voltage in a chip, an external capacitor needs to be connected to the LDO output pin LDO_CAP. The capacitor needs to be close to the LDO_CAP pin. If the chip series has multiple LDO output pins, each LDO output pin requires an external capacitor.
According to different NuMicro? Family series, the value of an external capacitor for LDO_CAP may be different. Please refer to the following table:
In addition, LDO_CAP can be connected to a 0.1uF bypass capacitor to filter high frequency noise.
