Figure 266. Power Saving LDO Configurations
CHOOSING LDO CONFIGURATION
Before choosing the proper LDO configurations, it is important to understand the power domains used in the system. The LDO
configurations will vary depending on the use of RF channels, internal/external LO or if an external VDDA_1p0 is supplied. Care is
needed when setting the LDO modes to avoid any potential of incorrect voltages getting supplied to internal blocks.
Table 110 shows the LDO operating modes. The enumerators for each of the modes are used when setting up the
adi_adrv9001_powermanagement_Configure function.
Table 110. LDO mode for power saving configurations
Enumerator
1 ADI_ADRV9001_LDO_POWER_SAVING_MODE_1 Normal LDO operation.
2 ADI_ADRV9001_LDO_POWER_SAVING_MODE_2 LDO always off. Input and output of the LDO connected to ground. Used when a power
domain is not required.
3 ADI_ADRV9001_LDO_POWER_SAVING_MODE_3 Not used.
4 ADI_ADRV9001_LDO_POWER_SAVING_MODE_4 Not used.
5
ADI_ADRV9001_LDO_POWER_SAVING_MODE_5
LDO bypassed. Supply an external source at the level expected at the LDO output (1v, Low
noise, 2.5% tolerance)
LDO mode 1 (Normal operation): The LDO is in a normal mode of operation. It is used to generate an on-chip voltage.
LDO mode 2 (LDO always off via PCB wiring): An LDO is not required and is permanently powered down via shorting its Input pin, and
its Output pin (if available) to ground on the PCB. Generally, this mode is used if the entire power domain is not required. No software
control of the LDO is available.
