Register Programming Examples

Example 1. Setting register 8h’12 value to 8h’3E’ will enable LDOs 1–5.

Example 2. Setting register 8h’39 to 8h’CC’ will set LDOs 1 and 2 to 3.0V. These voltages will appear at the LDO outputs if the

corresponding LDO has been enabled. Programming a voltage value to a LDO, which is off, will affect the LDO output voltage

after the LDO is enabled. Enabling and programming the output voltage are separate operations.
