onsemi Voltage Regulators - Linear KA79M12RTM

The KA79M12RTM is a 3-terminal linear voltage regulator designed to provide a fixed output voltage of -12V with a maximum output current of 0.5A. It features internal thermal overload protection and short circuit current limiting, ensuring reliable operation under various conditions. The device can handle input voltages up to -35V, with a dropout voltage of 1.1V at 500mA output current. The operating temperature range is from 0¬8C to +125¬8C, and it has a thermal resistance of 5¬8C/W from junction to case and 65¬8C/W from junction to air. Line regulation is specified at 50mV for input voltages between -7V and -25V, while load regulation is within 100mV for output currents ranging from 5mA to 500mA. The KA79M12RTM is suitable for applications requiring a stable negative voltage supply without the need for external components.
