LM338

Single Output Power Supply 12V / 5A based on LM338

This Single output 12 V / 5A power supply provides power for equipment that requires a large energy (Audio amplifier for car radio, CB, etc.). It is built around a voltage regulator like the LM338 and capable of providing voltages between 12V and 15 V (13.8 V for example). This circuit can provide a maximum […]

LM338 / LM350 / LM317 VOLTAGE REGULATOR CALCULATOR

You can use this calculator to vary the value of the program resistor (R1) and output set resistor (R2) and calculate the output voltage for the LM317 / LM338 / LM350 family of three terminal adjustable regulators. This calculator will work for most DC Voltage Regulators with a reference voltage (VREF) of 1.25. Typically, the […]
