Product Summary

The L78M12CDT-1 is a three-terminal positive regulator. It is available in TO-220, TO-220FP, DPAK and IPAK packages and with several fixed output voltages, making it useful in a wide range of applications. The L78M12CDT-1 can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, the L78M12CDT-1 can deliver over 0.5A output current. Although designed primarily as fixed voltage regulators, the L78M12CDT-1 can be used with external components to obtain adjustable voltage and currents.
