7.5V Step-Up Voltage Regulator U3V40F7

This compact (0.6″×0.6″) switching step-up (or boost) voltage regulator efficiently generates 7.5 V from input voltages as low as 1.3 V and handles continuous input currents up to 4 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.
