| Symbol | Description | Min. | Typ. | Max. | Units |
|---|---|---|---|---|---|
| VDDOUT |
VDD output voltage. |
1.8 | 3.3 | V | |
| VDDOUT,ERR |
VDD output voltage error (deviation from setting in ). |
-10 | +5 | % | |
| IEXT,OFF |
External current draw1 allowed in high voltage mode (supply on VDDH) during System OFF. |
1 | mA | ||
| IEXT,DCDC |
External current draw1 allowed in High Voltage mode (supply on VDDH) when VREGMAIN and VREGRADIO are in DC/DC mode. Assumes worst-case power consumption from both cores2, and at the lowest VDD output voltage setting. |
7 | mA | ||
| IEXT,LDO |
External current draw1 allowed in High Voltage mode (supply on VDDH) when VREGMAIN and VREGRADIO are in LDO mode. Assumes worst-case power consumption from both cores2, and at the lowest VDD output voltage setting. |
1 | mA | ||
| VREGH,DROP |
Required difference between input voltage (VDDH) and output voltage (VDD, configured in VREGHVOUT), VDDH > VDD |
0.3 | V |
1 External current draw is defined as the sum of all GPIO currents and the current being drawn from VDD.
2 In practice, the maximum external current draw is limited by the maximum output current of VREGH, subtracting the actual current being drawn from VDD.
