Pololu 5V Step-Up Voltage Regulator U3V12F5

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.

The regulator’s thermal shutdown prevents damage from overheating, but it does not have short-circuit or reverse-voltage protection.

 

 

Features

  • input voltage: 2.5 V – VOUT
  • fixed 5 V, 9 V, or 12 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
  • small size: 0.515″ × 0.32″ × 0.1″ (13 × 8 × 3 mm)

Using the Regulator

Connections

The boost regulator has three connections: input voltage (VIN), ground (GND), and output voltage (VOUT).

The input voltage, VIN, must be at least 2.5 V and should not exceed the output voltage, VOUT. Please be wary of destructive LC spikes that might cause the input voltage to exceed VOUT (see below for more information).

The three connections are labeled on the back side of the PCB, and they are arranged with a 0.1″ spacing along the edge of the board for compatibility with solderlessbreadboardsconnectors, and other prototyping arrangements that use a 0.1″ grid. You can solder wires directly to the board or solder in either the 3×1 straight male header strip or the 3×1 right-angle male header strip that is included.
