The Alpha Geek – Geeking Out

SparkFun – Voltage Regulator – 5V

SparkFun COM-00107 Mk01

SparkFun COM-00107 Mk02

SparkFun COM-00107 Mk03

SparkFun: COM-00107

Description: This is the basic L7805 voltage regulator, a three-terminal positive regulator with a 5V fixed output voltage. This fixed regulator provides a local regulation, internal current limiting, thermal shut-down control, and safe area protection for your project. Each one of these voltage regulators can output a max current of 1.5A.

Features:

  • Output Voltage: 5V
  • Output Current: 1.5A
  • Thermal Overload Protection
  • Short Circuit Protection
  • Output Transition SOA Protection

SparkFun – Voltage Regulator – Adjustable

SparkFun COM-00527 Mk01

SparkFun COM-00527 Mk02

SparkFun: COM-00527

Description: This is the LM317TG voltage regulator, a three-terminal positive regulator with a 1.2V to 37V adjustable output voltage. This adjustable regulator provides a local regulation, internal current limiting, thermal shut-down control, and safe area protection for your project. Did we mention that this guy is easy to use? It only requires two external resistors to set the output voltage. Each one of these voltage regulators can output a max current of 1.5A.

Features:

  • Output Voltage: 1.2V – 37V Adjustable
  • Output Current: 1.5A
  • Thermal Overload Protection
  • Short Circuit Protection
  • Output Transistor Safe
  • Floating Operation for High Voltage Applications

SparkFun – ProtoBoard – Rectangle Wired 3″

SparkFun PRT-08812 Mk01

SparkFun PRT-08812 Mk02

SparkFun PRT-08812 Mk03

SparkFun: PRT-08812

Description: This is a different kind of perf board. 3″ long and 2″ wide, the holes are plated through and PCB is double sided like you would expect. All holes are routed together on both sides. The really neat thing about this board is every pad has a 20mil width trace connecting to every other pad. Every pad is shorted together! This actually speeds up prototyping because instead of having to wire from one point to another, you simply cut the traces to isolate the route or pad you want to use. Your board will look a lot better and be more robust without lots of point to point wires to interfere. Standard 0.1″ spacing with a 4-40 (3mm) holes for mounting. Great for quickly prototyping stackable circuits.
