Pololu 12V Step-Up/Step-Down Voltage Regulator S10V2F12

Input voltage: 2.5 V to 18 V (can be higher than, the same as, or lower than the 12 V output)

Fixed 12 V output with 4% accuracy

Typical continuous output current: 200 mA (actual continuous output current depends on input voltage; see Typical Efficiency and Output Current section below for details)

<2 mA typical no-load quiescent current

Integrated over-temperature shutoff, Small size: 0.40 × 0.575 × 0.1 (10 mm × 15 mm × 3 mm)

This switching regulator uses the SEPIC topology to produce 12 V from input voltages between 2.5 V and 18 V. The wide input range coupled with its ability to convert both higher and lower input voltages makes it useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below 12 V. The compact (0.4 × 0.575) module can supply over 200 mA in typical applications.
