Pololu 3.3V Step-Up Voltage Regulator U1V10F3
This tiny (0.35″×0.45″) U1V10F3 switching step-up (or boost) voltage regulator efficiently generates 3.3 V from input voltages as low as 0.5 V. Unlike most boost regulators, the U1V10F3 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.
Alternatives available with variations in these parameter(s): output voltage.
