Voltage Regulators: NJR

JRC's regulators are world-class, reliable... and very convenient. Take a look, for example, at the NJM7800 and 7900 series of "isolated" regulators. Packaged in the popular TO-220 outline and nearly indestructible due to their internal current-limiting, thermal shutdown, and safe-area compensation, they require no insulating washer so mounting and heat-sinking is fast and convenient.
