The RT5133 is an integrated Power Management IC for portable devices,
|
|
featuring 8 LDOs and 3 GPOs. It allows programmable output voltages,
|
|
soft-start times, and protections via I2C. GPO operation depends on LDO1
|
|
voltage.

Over Current state.

If set to true, all LDO channels will be shut down.

If set to false, only the affected LDO channel will shut down itself.

Properties for the base regulator, which is the top-level supply for

LDO1 to LDO6. It functions merely as an on/off switch rather than
|
|
regulating voltages. If none of LDO1 to LDO6 are in use, switching
|
|
off the base will reduce the quiescent current.
