Figure 21 DC-DC Boost Converter Connections
Note that the recommended output capacitor COUT varies according to the required output voltage.
The DC4_RANGE register field must be set according to the required output voltage.
See Section 30.4 for details of specific recommended external components.
15.16 LDO REGULATOR OPERATION
15.16.1 OVERVIEW
The WM8310 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 WM8310 is in the OFF
state. The principal characteristics of the LDO Regulators are shown below.

Table 47 LDO Regulator Overview
15.16.2 LDO REGULATORS
The LDO Regulators are configurable circuits which generate accurate, low-noise supply voltages for
various system components. The LDO Regulators are dynamically programmable and can be re-
configured at any time. Two low power modes are provided for the general purpose LDOs 1-6; a
single low power mode is provided for the analogue LDOs 7-10; this enables the overall device power
consumption to be minimised at all times.
