The recommended output capacitor COUT varies according to the required transient response. Note
that the DCm_CAP register field must be set according to the output capacitance on each DC-DC
Converter in order to achieve best performance.
See Section 30.3 for details of specific recommended external components.
15.15 LDO REGULATOR OPERATION
15.15.1 OVERVIEW
The WM8321 provides 11 LDO Regulators. Four of these are low-noise analogue LDOs. One of the
LDO Regulators (LDO11) can be configured to be enabled even when the WM8321 is in the OFF
state. The principal characteristics of the LDO Regulators are shown below.
