Key Features:

  • Input voltage: 2.5 V – VOUT
  • Fixed 5 V output with 4% accuracy
  • 1.4 A switch allows for input currents up to 1.4 A
  • 2 mA typical no-load quiescent current
  • Integrated over-temperature shutoff

The compact (0.32″×0.515″) U3V12F5 switching step-up (or boost) voltage regulator takes an input voltage as low as 2.5 V and efficiently boosts it to 5 V. The pins have a 0.1″ spacing, making this board compatible with standard solderless breadboards and perfboards. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and have a typical efficiency between 80% to 90%. The available output current is a function of the input voltage, output voltage, and efficiency, but the input current can typically be as high as 1.4 A.
