The bypass capacitors on the Low-Dropout Regulator (LDO) outputs are available when the load switches are in LDO mode.
For LDO mode, connect jumpers between pin 1 and 2 on pin header P16 for LDO1 and pin 3 and 4 for LDO2. The following figure describes the jumper configuration for LDO bypass capacitors.
Figure 1. Bypass capacitors on the LDO output
| PMIC pin | Connected configuration | Connected jumper pins | Comment |
|---|---|---|---|
| VOUTLDO1 | LDO_BYPASS1 (20 µF) | P16 pin 1 to pin 2 | Denoted as 2 on the EK |
| VOUTLDO2 | LDO_BYPASS2 (20 µF) | P16 pin 3 to pin 4 | Denoted as 1 on the EK |
Note: Ensure the LDO bypass capacitors are disconnected when the load
switches are not in LDO mode.
