This compact (0.45″×0.6″) U1V11F5 switching step-up (or boost) voltage regulator efficiently generates 5 V from input voltages as low as 0.5 V. Unlike most boost regulators, the U1V11F5 offers a true shutdown option that turns off power to the load, and it automatically switches to a linear down-regulation mode when the input voltage exceeds the output. The pins have a 0.1″ spacing, making this board compatible with standard solderless breadboards and perfboards.

1 - Without included optional headers.
2 - Regulator may overheat at lower input currents when VIN is much lower than VOUT. Available output current is a function of VIN, VOUT, and the regulator efficiency.
3 - The highest quiescent currents occur at very low input voltages; for most of the input voltage range, the quiescent current is well below 1 mA.
