MC7808CD2TG is a three-terminal low drop-out (LDO) voltage regulator with an adjustable output voltage that range from 1.2V to 15V. It is commonly used in embedded system and telecommunication applications. The product is available in space-saving SOT-223 and DDPAK package.

The output voltage of the MC7808 is internally adjustable to as low as 1.2V and as high as 15V. This product is ideal for different power requirements, as it offers several features such as temperature regulation, short-circuit protection and over-temperature shutdown. Further, it is designed to offer superior line regulation, load regulation and turn-on accuracy.

An MC7808CD2TG regulator can be used in a wide range of applications such as PC motherboard, DECT, keyless entry systems, wireless networking, desktop/notebook computer, LCDs/notebooks/servers, and automotive. These applications typically require a reliable voltage source specifically expressed as a linear voltage regulator.

The MC7808CD2TG is a type of linear regulator which uses an external resistor divider to adjust the output voltage. The main component of this three-terminal voltage regulator is a P-channel MOSFET. It consists of two inputs – Vin and Vout; and one output – Vout. When the input voltage is greater than the output voltage, the regulator supplies current to the load connected at the output. When the input voltage is lower than the output, the regulator switches off the P-channel MOSFET to reduce the flow of current from the output.

The voltage drop across the device is low, hence the regulator is suitable for use with low ESR capacitors. It offers a fast turn-on time and high power supply rejection ratio (PSRR). Additionally, the device operates over a -40°C to +85°C temperature range with an input voltage range from 3V to 20V.

In summary, the MC7808CD2TG is a three-terminal adjustable voltage regulator with a maximum output current of 800mA. The device is widely used in embedded system and telecommunication application. It offers superior line regulation, low dropout voltage and low quiescent current as compared to other linear voltage regulators. It is available in SOT-223 and DDPAK packages, and has a wide operating temperature range of -40°C to +85°C.
