ONSEMI MC78M09BDTG Positive Voltage Regulator

The MC78M09BDTG is a positive voltage regulator capable of providing a 9V output. It is similar to standard 3-terminal regulators but is designed for applications requiring lower output current, with a maximum of 500mA when properly heat sinks are used. The device incorporates internal circuitry for current limiting, thermal shutdown, and safe-area compensation, ensuring reliable operation under various conditions. It requires no external components, offers high accuracy within ±2%, and is suitable for local power regulation in automotive, industrial, and power management applications.
