MC7912CD2TG

The MC7912CD2TG is a voltage regulator, specifically a linear voltage regulator, and as such it is used in a variety of applications. The regulator is a two-terminal device which provides a constant output voltage during normal operation, and operates over the operating temperature range of 0°C to +85°C.

The MC7912CD2TG is a negative voltage regulator, providing a regulated negative output voltage of -12V, with a total maximum output current of 1A. It is a three-terminal device, with input and ground connected to the regulating terminal. It is designed to provide a low output impedance, with a minimum load current of 50 mA, in order to ensure that the output voltage remains constant over a wide range of line and load variations.

In terms of its working principle, the MC7912CD2TG is a three-terminal linear device that works by sensing the output voltage and comparing it to an internal reference voltage. A voltage comparator circuit then compares the two voltages and consequently the output current will either increase or decrease in response to a change in the output voltage. This voltage-compensated technique allows for the output voltage to remain relatively constant, even when faced with line and load variations.

The MC7912CD2TG is a negative voltage regulator with its most common application being in power supplies. It is used to regulate both the AC and DC voltage from the power supply, providing a regulated and stable output voltage. This ensures that the voltage output from the power supply does not vary and, as such, ensures that varying loads will be supplied with the correct voltage without having to adjust the voltage setting on the power supply.

Other applications of the MC7912CD2TG include use in battery-driven systems and consumer electronics. Battery-driven systems require a far lower output voltage level, typically between 1V and 5V, and the MC7912CD2TG is ideal for such applications as it is able to provide a regulated voltage at the low minimum of 1V, while also having a low dropout voltage. In terms of consumer electronics, the MC7912CD2TG is used in various types of products to provide a consistent and stable output voltage, such as in televisions, audio amplifiers, and DVD players.
