3.3V Step-Up Voltage Regulator U3V16F3

This compact (0.32″×0.515″) switching step-up (or boost) voltage regulator efficiently generates 3.3 V from input voltages as low as 1.3 V and handles continuous input currents up to around 1.6 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.
