12V Step-Up Voltage Regulator U3V40F12
This compact (0.6″×0.6″) switching step-up (or boost) voltage regulator efficiently generates 12 V from input voltages as low as 1.3 V and handles continuous input currents up to 3.5 A. (Note: minimum start-up voltage is 2.7 V, but it operates down to 1.3 V after that.) The pins have a 0.1″ spacing, making this board compatible with standard solderless breadboards and perfboards.

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.
