The MC7912BTG is an integrated circuit (IC) component belonging to the MC79xx series of voltage regulators. It is a negative voltage regulator that can provide a fixed output voltage of -12 volts (V) with a maximum output current of 1 ampere (A). The MC7912BTG is widely used in a variety of electronic applications where a stable and regulated negative voltage is required.
Key features of the MC7912BTG include:
1. Output Voltage: The IC is designed to provide a regulated output voltage of -12V. This voltage remains constant even under varying load conditions.
2. Maximum Output Current: The MC7912BTG can handle a maximum output current of 1A. This current rating determines the maximum load that can be connected to the regulator without causing any damage.
3. Voltage Regulation: The IC ensures a stable output voltage by using a series pass transistor in conjunction with a negative feedback circuit. This feedback loop adjusts the transistor's resistance to maintain a constant output voltage, compensating for any changes in load or input voltage.
4. Thermal Overload Protection: The MC7912BTG incorporates a thermal shutdown feature that prevents the IC from overheating. If the temperature exceeds a certain threshold, the IC will shut down to protect itself and the connected circuitry
