|
| 1.5V Control. LDO voltage regulator output to drive external pass transistor. If 1.5V is |
CTRL_15 | A | already present in the system, leave output unconnected. To achieve optimal D3 power |
|
| consumption (<50 mw), leave the output unconnected and use a |
|
| external switching regulator. |

| 2.5V Control. LDO voltage regulator output to drive external pass transistor. If 2.5V is |
CTRL_25 | A | already present in the system, leave output unconnected. To achieve optimal D3 power |
