IC REG LINEAR 12V 500MA DPAK


Bypass caps, pull-ups, strapping resistors, custom silkscreen & more
Design a Custom BoardFixed output positive voltage regulator delivering 500mA at 12V with ±2% output voltage tolerance. Features internal current limiting, thermal shutdown, and safe area protection for robust operation across extended temperature ranges. Commonly used for local on-card regulation in power supply circuits, eliminating distribution losses in larger systems.
TO-252 power MOSFETs require careful hand-soldering due to the large drain tab and tight 4.56mm lead spacing, making a breakout board essential for reliable prototyping. This board converts the package to breadboard-compatible headers and standard 0.1-inch pitch, eliminating soldering risk and enabling rapid circuit iteration for power switching applications.
