Introduction
The NCP7805CTG is a high-efficiency, low-dropout (LDO) linear voltage regulator designed for portable applications. It is a single low-dropout regulator that operates from a 1.5V to 5.5V input voltage and provides a fixed 5V output voltage. The device features low quiescent current, low output noise, low maximum dropout voltage, a low shutdown current, and a fast response time (from off to on). It is also available in thermally-enhanced, high-density leaded packages.
This device offers a wide range of features and benefits that make it attractive in a variety of applications, including portable electronics and telecom equipment, as well as embedded applications. The NCP7805CTG provides fast transient response, high output current capability and low dropout voltage, making it an ideal choice for applications with large dynamic loads.
Application Field
NCP7805CTG voltage regulator is suitable for a wide range of portable and embedded applications, including cellular phones, PDAs, media players and other handheld devices, as well as automotive and telecommunications equipment. The device offers high reliability and excellent performance for these applications, making it an attractive choice.
It is also an ideal choice for applications that require a stable 5V voltage supply, such as PC server, personal computer, LCD monitor, peripheral device, solid state drive, valve amplifier, blue LED, etc. The low noise operation of the NCP7805CTG is specifically tailored to the needs of noise sensitive circuits such as those used in audio systems. In addition, the device can be used in space limited applications, such as in microcontroller boards, where a low-profile package is required.
The NCP7805CTG is capable of providing up to 1A of output current and has a low dropout voltage which provides good thermal performance. This makes it suitable for many high current applications, including automotive applications requiring a stable, clean power supply.
Working Principle
NCP7805CTG linear voltage regulator works on the principle of comparison and control. A reference voltage is compared with output voltage. The difference between reference voltage and output voltage is called the error voltage. When the output voltage is too high, the error voltage is positive, and the output of the comparator, which is high, will turn on the transistor, so the current will be diverted, the output voltage is reduced.
When the output voltage is too low, the error voltage is negative, and the comparator output is low, which will turn off the transistor, so the current is allowed to flow back, the output voltage is increased. This process of regulating the output voltage is called “regulating voltage”.
The NCP7805CTG is designed to have a minimum dropout voltage of 0.2V, which ensures a high efficiency of up to 96% over the full operating temperature range and input voltage range (1.5V to 5.5V). The device also features a fast response time of 10us, which ensures a stable and accurate output voltage.
Conclusion
In conclusion, the NCP7805CTG linear voltage regulator is a reliable, flexible and efficient device that is suitable for a wide range of applications. It offers excellent transient response, low dropout voltage, high output current capability and low noise operation, making it ideal for noise sensitive applications. The device is available in a wide range of packages and provides a wide range of benefits for portable and embedded applications.
