4.5-20V Fine-Adjust Step-Up Voltage Regulator U3V70A
This powerful synchronous switching boost regulator efficiently generates a finely adjustable output voltage between 4.5 V to 20 V from an input voltage as low as 2.9 V while using an input current as high as 8 A. This regulator features reverse voltage protection, and unlike most boost regulators, it offers a true shutdown option that turns off power to the load.

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 12-turn potentiometer.
