Design a Custom BoardAbout This Component
Fixed output negative voltage regulator delivering -5V at up to 500mA in a compact DPAK surface-mount package. Features internal thermal shutdown, short-circuit current limiting, and safe-area compensation for robust operation. Requires minimal external components and serves as the negative complement to MC78M00 positive regulators in dual-supply applications.
Package: TO-252-2 · 3 pins
Why does this need a breakout?
This 3-pin SMD package is difficult to hand-solder due to tight pin spacing and thermal requirements typical of power switching applications. A breakout board breaks out each pin to standard headers, enabling reliable breadboard prototyping and reducing cold-joint risk during development without needing a reflow oven or hot air station.
