onsemi Voltage Regulators - Linear MC79M08BDTG

The MC79M08BDTG is a fixed output negative voltage regulator from the MC79M00 series, designed to provide a nominal output voltage of -8.0 V. It is capable of delivering output currents up to 500 mA with appropriate heatsinking. The device features internal thermal overload protection, short circuit current limiting, and safe-area compensation, ensuring robust performance under various operating conditions. This regulator requires no external components for operation and is available in both DPAK and TO-220 packages. The input voltage range is specified from -10.5 V to -25 V, with a dropout voltage of approximately 1.1 V at full load. Line regulation is rated at 5.0 mV for input voltages between -10.5 V and -25 V, while load regulation is 30 mV for output currents ranging from 5.0 mA to 500 mA. The device also exhibits good ripple rejection, with values around 63 dB at 120 Hz. The MC79M08BDTG is suitable for applications requiring a stable negative voltage supply, making it a viable choice for engineers looking for reliable voltage regulation in their designs.
