The compact (0.32"×0.515") U3V12F9 switching step-up (or boost) voltage regulator takes an input voltage as low as 2.5 V and efficiently boosts it to 9 V. The pins have a 0.1" spacing, making this board compatible with standard solderless breadboards and perfboards.

  

 

OverviewThese boost (step-up) voltage regulators generate higher output voltages from input voltages as low as 2.5 V. 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 (see Typical Efficiency and Output Current section below), but the input current can typically be as high as 1.4 A. This regulator is available with a fixed 5 V, 9 V, or 12 V output:

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

We have several other boost regulators that you might consider as alternatives to these:

- 3.3V or 5V boost regulator NCP1402 – lower-current alternatives that work with input voltages as low as 0.8 V. 
- Adjustable boost regulator 2.5-9.5 V – output voltage is adjustable from 2.5 to 9.5 V; works with input voltage as low as 1.5 V. 
- Adjustable boost regulator 4-25 V – output voltage is adjustable from 4 to 25 V; works with input voltage as low as 1.5 V. 

  

 

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 RegulatorConnectionsThe 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 dest...
