Keep in mind that for your requirement, the regulator would need to dissipate (230 - 19) = 211 volts at up to 1 ampere = up to 211 watts as heat. This is a huge amount of heat generated, totally impractical for linear regulators. Consider using a 15 volt wall wart instead, and regulate its output to the required 13 volts. | |
