Tsukure Mad Labs Ampere / Current Booster

Volt regulators such as the LM708, and LM317 series (and others) sometimes need to provide a little bit more current then they actually can handle. If that is the case, this little circuit can help out. Power power transistors can be used to boost the extra needed current above the maximum allowable current provided via the regulator.

Current up to 1500mA(1.5amp) will flow through a regulator, anything above that makes the regulator conduct and adding the extra needed current to the output load. You may also stack power transistors for even more current.

NOTE: Both regulator and power transistor must be mounted on an adequate heatsink.

Let's Get Started!

Below you will find a list of bits to gather before hand, followed by a detailed schematic. Using a breadboard lay out the components and connect them together as shown. Alternatively you can purchase this module from our shop and simply solder the components in the places indicated on the quality assured printed circuit boards provided.


What You Need...


2 470uF Capacitor (Polarized)
2 PCB Mount 2-Pin Screw Terminal Block Connector (Other)
1 10R
[ Brown, Black, Black, Gold ]
Resistor (0.25 Watt)
1 1R
[ Brown, Black, Black, Silver ]
Resistor (0.25 Watt)
1 TIP2955 Transistor (PNP)
1 LM7812 Voltage Regulator

NB: Any resistor colour codes specified relate to 5 band resistor codes, the 5th band has not been shown intentionally. The 5th band indicates the resistor tolerence, we use only the highest tolerence resistors in our products.
