4.5-20V Fine-Adjust Step-Up Voltage Regulator U3V70A
| Output voltage | Typical max input current* | Min input voltage |
|---|---|---|
| 4.5 V – 20 V | 8 A | 2.9 V |
*Actual achievable 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 or terminal blocks. Height with terminal blocks installed is approximately 0.5″.
- 2
- Without included optional headers or terminal blocks. Terminal blocks add 3.4 g.
- 3
- The operating voltage should not exceed the set output voltage, VOUT.
- 4
- Instantaneous. This is the rating for the switch, and regulator actively limits input current to this. Sustainable input current depends on input and output voltage and external conditions like ambient temperature and airflow.
- 5
- Output voltage is set by a built-in precision 11-turn potentiometer.
