Design a Custom BoardAbout This Component
Negative linear regulator IC providing adjustable output voltage from -1.2V to -37V at up to 1.5A output current. Features internal current limiting and thermal shutdown protection. Commonly used in dual-supply systems, negative bias networks, and general-purpose negative voltage regulation applications requiring moderate current.
Package: SOT-223-3 · 3 pins
Why does this need a breakout?
SOT-223 three-pin regulators and transistors are difficult to hand-solder due to tight 1.5mm pitch and heat-sinking requirements. A breakout board brings standard 0.1" header spacing, eliminating soldering challenges and enabling immediate breadboard prototyping without rework or micro-soldering tools.
