# Electrical Characteristics (ESP32-S2)

## DC Operating Conditions

| Parameter | Symbol | Min. Value | Nom. Value | Max. Value | Unit |
| - | :-: | :-: | :-: | :-: | :-: |
| Supply Voltage | VSUP | +2.80 | +5.00 | +5.50 | V |
| Operating Voltage | VOP | +2.80 | +3.30 | +3.60 | V |
| Output Voltage | V3V3 | – | +3.30 | – | V |
| Output Voltage\* | V5V | – | +5.00 | – | V |
| Operating Temperature | TOP | -40 | – | +125 | °C |

\*Note: The output voltage on the 5V pin is equal to the voltage of the power source supplying the product via the USB connector.
