A voltage regulator consists of 6 terminations. Due to its 225 high peak reflow temperature, this voltage regulator 12v is virtually indestructible. I would like to point out that this voltage regulator belongs to the Switching Regulator or Controllers subcategory. There is a possibility that DC DC switching regulator can give voltage at 1.6V volts. There should be a voltage regulator's maximum operating temperature of 85°C or less. A DC DC switching regulator's minimum operating temperature of -40°C should be exceeded.
