Learn More lm78112 opens in a new window or tab Any international shipping is paid in part to Pitney Bowes Inc. The output voltage is adjusted using a couple of resistors, and one of these resistors can be replaced with a potentiometer to give an adjustable output.
With this set up, the power transistor and power resistor need heatsinkingand selecting the correct specification of transistor and resistor, and getting everything set up is not particularly easy.

The benefit of this first schematic is that the output is actually regulated; the PNP is fully in the feedback loop. Regulators for higher currents than 1 Amp are available, but tend to be expensive, and still require good heatsinking.
It is worth noting however that this approach to load balancing makes the voltage regulation a bit less accurate. Learn More – opens in a new window or tab. By adding transistors as shown in the schematics above high output currents at the regulated voltage can be output.
