5V Step-Up Voltage Regulator U3V40F5
| Output voltage | Typical max input current* | Min input voltage |
|---|---|---|
| 5 V | 4 A | 1.3 V (2.7 V startup) |
*Actual achievable maximum continuous current is a function of input voltage and is limited by thermal dissipation. See the output current graphs on the product pages for more information.

Notes:
- 1
- Without included optional headers.
- 2
- Note: the minimum startup voltage is 2.7 V, but the regulator can operate down to 1.3 V after startup.
- 3
- Instantaneous. This is the rating for the switch, and regulator actively limits input current to this while boosting. Sustainable input current depends on input and output voltage and external conditions like ambient temperature and airflow.
