FAQs

What is MC79M12BDTG?

The MC79M12BDTG is a fixed negative voltage regulator integrated circuit (IC) manufactured by ON Semiconductor. It is designed to provide a constant output voltage of -12V and is commonly used in power supply and voltage regulation applications.

How Does MC79M12BDTG Work?

The MC79M12BDTG regulates the output voltage by comparing a reference voltage to the feedback voltage from the output. It then adjusts its internal pass transistor to maintain a stable output voltage, even with varying input voltages and load conditions. The IC can handle a maximum output current of 0.5A, making it suitable for low-power applications.

How Many Pins does MC79M12BDTG have and What are the Functions of the Pinout Configuration?

The MC79M12BDTG is housed in a 3-pin DPAK (TO-252) package. The pinout configuration includes:

Input (VIN): The input voltage is applied to this pin, which is typically connected to the unregulated DC input voltage.
Ground (GND): The ground pin serves as the reference point for the IC and is connected to the system ground.
Output (VOUT): The regulated output voltage is obtained from this pin and connected to the load or the circuit requiring the -12V supply.

What are the Pros and Cons of MC79M12BDTG?

Pros:

Fixed Voltage Regulation: Provides a stable -12V output voltage, eliminating the need for external voltage regulation components.
Thermal Shutdown Protection: Includes built-in thermal shutdown protection to prevent damage due to overheating.
Simple Design: Requires minimal external components for voltage regulation, simplifying system design and reducing component count.

Cons:

Fixed Output Voltage: The output voltage is fixed at -12V and cannot be adjusted.
Low Output Current: Limited to a maximum output current of 0.5A, which may not be sufficient for high-power applications.

Are There Any Equivalents/Alternatives to MC79M12BDTG for Recommendation?

The LM7912CT from Texas Instruments is an equivalent -12V voltage regulator with similar features.
Alternatives to the MC79M12BDTG include the L7912CV from STMicroelectronics and the UA79M12CKCS from Texas Instruments.
