Added to your shopping cart

The BD10KA5W is a low-saturation regulator with an output voltage precision of ±1%. It also has built-in overcurrent protection that prevents the destruction of the IC, due to output short circuits and a thermal shutdown circuit.

  • Max Output Current : 500mA
  • Output Voltage Precision : 1.0V ±1%
  • Built-in Overcurrent Protection Circuit
  • Built-in Thermal Shutdown Circuit
  • Shutdown Switch
  • Operating Temperature Range : -40C to +105C

Voltage Regulator - BD10KA5W (500mA) Product Help and Resources

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

3 Soldering

Skill Level: Competent - You will encounter surface mount components and basic SMD soldering techniques are required.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

Customer Comments

  • Does anybody have an interesting use for this part that they would like to share?

  • Dearest (Insert Sparkfun Employee name here),
    I would truly appreciate a listing of the output voltage of this regulator listed in the description.
    With Thanks,
    Josh Franz

    • Key information would be a great time saver, it can be a pain looking at each page looking for a part that has the critical spec your after.

      Example:

      Triple Axis Accelerometer Breakout - MMA7361

      Could be

      MMA7361 - Triple Axis Accelerometer - ±1.5g and ±6g - Analog - 2.2 - 3.6 VDC (3.3V)

    • Check the datasheet above. The model number is BD10KA5WF. Therefore it’s a 1.0v, as stated above.

      • Why not go the extra inch and change the title to “1.0v Voltage Regulator”, since the output voltage is kind of a critical parameter.

      • Put Voltage output: 1.0V AT LEAST in the features, this description is definitively misleading. I guess how many people bought this expecting an adjustable voltage output.

  • So these are the 1.0 Volt regulators?

    • Yes, they are. The first two numbers represent the voltage (Eg: 10>1.0V, 12>1.2V, etc).

      Note: This comment has been updated after reading a comment by User 11952 (I read the part number incorrectly at first).

  • This IS in the SFE Eagle library, under the name BD10KA5WF-E2.
