NCV7808BDTG is an advanced low-dropout (LDO) linear voltage regulator specifically designed to power automotive applications. With a maximum dropout voltage of 0.3V, the NCV7808BDTG provides for far lower output voltages to be powered than in conventional systems. It is well-suited for automotive applications such as providing pre-regulator for power supplies for memory and microcontroller, providing bias voltage for transceiver, and providing ultra-low voltage (1.5V-1.9V) from which a microcontroller can be operated.

The NCV7808BDTG is a fixed output 3-pin LDO regulator with a maximum dropout of 0.3V and a maximum output current of up to 3A. The integrated circuit features an advanced bias control system and a low quiescent current of only 5 μA for shutdown. This LDO is also uniquely capable of delivering outputs up to 1.9V with extremely low dropout and excellent transient response.

By combining on-chip bias control, over-voltage and short-circuit protection, low-noise operation, and low quiescent current with the small 3-pin SOT-23 package, the NCV7808BDTG provides very high performance operation in small space.

The NCV7808BDTG operates with a range of input voltages between 2.25V to 14V and is capable of delivering outputs of 1.5V to 5V with extremely low voltage drops. It provides excellent transient response and high output accuracy. Additionally, the integrated LDO boasts over-voltage protection, and short-circuit protection paired with a soft-start feature to protect against any potential inrush current.

The application field of the NCV7808BDTG is widely and variously. It can be used to power automotive applications such as for providing pre-regulator for power supplies for memory or microcontroller, providing bias voltage for transceiver, and providing ultra-low voltage (1.5V-1.9V) from which a microcontroller can be operated. Also, it can be used in various industrial machinery, medical equipment, smartphones, smart home and many other applications. As for its working principle, it functions by allowing a controlled amount of current to flow from its input to its output when a load is placed at its output.

The NCV7808BDTG accepts an input voltage range of 2.25-14V, which can be typically powered with a 3V, 4V, 5V, 9V. Once the input voltage is applied, the output voltage of the LDO is regulated by an internal feedback mechanism. This feedback loop controls the amount of current being allowed to flow through the device in order to maintain a constant output voltage, regardless of load variations at the output. This is the basic working principle of the device.

In sum, NCV7808BDTG is a highly efficient and cost-effective low-dropout (LDO) linear voltage regulator, especially for automotive applications. With its on-chip bias control, over-voltage and short-circuit protection, low-noise operation, and low quiescent current, it provides high performance operation in small space. Its application field is numerous, such as automotive, industrial machinery, medical equipment, smartphones, smart home and many other applications. Its working principle is simple, which is by allowing a controlled amount of current to flow from its input to its output when a load is placed at its output.
