LDOTRIM? #25

What's the benefit of setting LDOTRIM? It's not clear in manual. Bigger consumption but more stable run?

got the reply:

Adjusting the voltage of the digital core of the chip can enhance or weaken the performance of the chip, and accordingly, the power consumption of the chip will also increase or decrease. This feature mainly allows customers to adjust the chip and power consumption to the appropriate range for their projects. However, we recommend that you should not adjust the digital core voltage of the chip.
