| description: | |
| The SC2731 integrates low-voltage and low quiescent current DCDC/LDO. |
| 14 LDO and 3 DCDCs are designed for external use. All DCDCs/LDOs have |
| their own bypass (power-down) control signals. It is recommended to use |
| external tantalum or MLCC ceramic capacitors with these LDOs. |
| Valid names for the regulators are: |
| BUCK: |
| BUCK_CPU0, BUCK_CPU1, BUCK_RF |
| LDO: |
| LDO_CAMA0, LDO_CAMA1, LDO_CAMD0, LDO_CAMD1, LDO_CAMIO, LDO_CAMMOT, |
| LDO_CON, LDO_EMMCCORE, LDO_SDCORE, LDO_SDIO, LDO_SRAM, LDO_USB33, |
| LDO_VLDO, LDO_WIFIPA |
