Description
R72
Load resistor for LDO0 rail
R9
Load resistor for LDO1 rail
R11
Load resistor for LDO2 rail
R8
Load resistor for Boost rail
If an external load needs to be applied to any rail, first remove the jumper previously installed on
LDO0/1/2_LD or VO_BST connector. Then apply the external load between '+' and '-' terminals of
LDO0/1/2_LD or VO_BST connector, as shown in Figure 7.
Make sure the load current always flows out of '+' terminal and flows into '-' terminal on the
connectors.
