onsemi Voltage Regulators - Linear MC79M12BT

The MC79M12BT is a fixed output negative voltage regulator from the MC79M00 series, designed to provide a nominal output voltage of -12 V with a maximum output current of 500 mA. It features internal thermal overload protection, short circuit current limiting, and safe-area compensation, ensuring reliable operation under various conditions. The device requires no external components for basic functionality and is available in both TO-220 and DPAK packages, with options for lead-free configurations. The input voltage range is specified from -14.5 V to -30 V, with a dropout voltage of approximately 1.1 V at full load. Line and load regulation are rated at 50 mV and 240 mV, respectively, at 25¬8C. The operating junction temperature range is from -40¬8C to +150¬8C, making it suitable for a wide range of applications.
