This compact (0.45″×0.6″) U1V11F3 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 U1V11F3 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.

Dimensions

Size: 0.45″ × 0.6″ × 0.1″1
Weight: 0.7 g1

General specifications

Minimum operating voltage: 0.5 V
Maximum operating voltage: 5.5 V
Maximum input current: 1.2 A2
Output voltage: 3.3 V
Reverse voltage protection?: N
Maximum quiescent current: 1 mA3

Identifying markings

PCB dev codes: reg12a
Other PCB markings: 0J7440

Notes:

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.
