Преобразователь напряжения повышающий U1V11 Pololu 5V Step-Up Voltage Regulator U1V11F5

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.

Features
Input voltage: 0.5 V to 5.5 V
Fixed 5 V output with 4% accuracy
True shutdown option that turns off power to the load
Automatic linear down-regulation when the input voltage is greater than the output voltage
1.2 A switch allows for input currents up to 1.2 A
Good efficiency at light load: <1 mA typical no-load quiescent current, though it can exceed 1 mA for very low input voltages (<100 ?A typical quiescent current with SHDN = LOW)
Integrated over-temperature shutoff
Small size: (12 ? 15 ? 3 mm)
