The L7808CD2T is part of a wide range of linear voltage regulators manufactured by ST Microelectronics. These discrete devices are designed to provide low dropout voltage regulation, keeping the output voltage stable with little variation across a variety of input voltages. The L7808CD2T is specifically designed to work with 8V output voltages and the 2A (2 A) current rating is the highest of all the L7808 linear voltage regulator families. The L7808CD2T is a Cost-Effective, ultra-low-power, 8V voltage regulator designed to maintain stable and accurate output voltage, regardless of changes in input voltage, load, or temperature.

The L7808CD2T works by using a pass transistor that reduces the input voltage to the level that is necessary for the set output voltage. It includes a fixed resistive voltage divider circuit connected between the output and reference terminals. When the voltage between the output and reference terminals is greater than the set value, the excess voltage is routed back to the input. This supply voltage feedback loop limits the output voltage to the desired value. Additionally, the L7808CD2T has a thermal shut off feature which will shut off the output in case of over temperature to further protect the device and provide reliable operation.

The L7808CD2T is a fairly common linear voltage regulator and can be used in a variety of applications. Its 8V output and 2A current rating make it suitable for a wide range of applications such as power supplies, battery chargers, and DC to DC converters, among others. It is also used in automotive electronics, digital audio, and industrial control applications, where it provides regulated power with high accuracy and steady output voltages. Additionally, it can be used in power management applications, power over Ethernet applications, voltage converters, charge pumps, and multiple other applications.

In terms of features, the L7808CD2T offers excellent line and load regulation, low dropout voltage, thermal shut off, and low quiescent current. It provides up to 2A of output current, and its low dropout voltage makes it well suited for low input voltage applications. It also features a thermal shut off feature which will shut off the output in case of over temperature, which further protects the device and provides reliable operation. Additionally, its low quiescent current consumption makes it an ideal choice for battery operated applications.

Overall, the L7808CD2T is an ideal choice for applications where low dropout voltage, low quiescent current, and high accuracy are of essence. Its use in power supplies, battery chargers, DC to DC converters, automotive electronics, digital audio, industrial control applications, power management applications, power over Ethernet applications, voltage converters, charge pumps, and multiple other applications makes it highly versatile. With its excellent line and load regulation, low dropout voltage, thermal shut off, and low quiescent current it is a great choice to meet a variety of requirements.
