I have some questions about SGTL5000 internal regulator.
Please see my questions below.
Please see LINREG_SIMPLE_POWERUP definition in Table 33 in SGTL5000 datasheet.
I want to know what is "simple (low power) digital supply regulator" and what block (or when) use this regulator.
According to this definition, it seems related to VDDD, but primary VDDD linear regulator is controlled by LINREG_D_POWERUP, so I'm confused.
Could you let me know it?
Please see Table 3 in SGTL5000ER (Rev.2.0).
Which regulator is indicated in this errata sheet?
simple (low power) digital supply regulator controlled by LINREG_SIMPLE_POWERUP?
or primary VDDD linear regulator controlled by LINREG_D_POWERUP?
