| 12 | +description: |
| 13 | + RT5033 is a multifunction device which includes battery charger, fuel gauge, |
| 14 | + flash LED current source, LDO and synchronous Buck converter for portable |
| 15 | + applications. It is interfaced to host controller using I2C interface. The |
| 16 | + battery fuel gauge uses a separate I2C bus. |

| 30 | + The regulators of RT5033 have to be instantiated under a sub-node named |
| 31 | + "regulators". For SAFE_LDO voltage there is only one value of 4.9 V. LDO |
| 32 | + voltage ranges from 1.2 V to 3.0 V in 0.1 V steps. BUCK voltage ranges |
| 33 | + from 1.0 V to 3.0 V in 0.1 V steps. |
