Over a 1.2V to 33V output range, the LM350K series of adjustable 3-terminal positive voltage regulators can produce more than 3A. They're quite simple to use, with only two external resistors needed to set the output voltage. The operating temperature of LM350K is 0°C~125°C and its maximum power dissipation is 30W. LM350K has 2 pins and it is available in TO-204AA and TO-3 packaging way.
