CS5204-1GT3

Planar Magnetics Inc CS5204-1GT3 is a monolithic integrated current mode and low drop-out (LDO) linear voltage regulator that provides constant voltage and current output.

What is CS5204-1GT3?

The CS5204-1GT3 is an integrated low drop-out (LDO) linear voltage regulator that supplies constant voltage and current output over a wide range of temperatures. It is a monolithic integrated device that incorporates a PMOS pass device and a current source in an efficient thermally compensated package. The LDO device reduces both field and thermal stress contributions. The device is easy to use and provides dynamic voltage scaling, sequencing, inrush current control and thermal protection features.

Applications for the CS5204-1GT3

The CS5204-1GT3 can be used in a variety of applications, ranging from wireless base stations to mobile phones and laptop computers, as well as point of sale (POS) systems. The device is ideal for use in low noise, low power audio and video systems, such as LCD and LED monitor power supplies. It is also suitable for automotive applications, including power conversions and auxiliary power supplies.

Working Principle of CS5204-1GT3

The CS5204-1GT3 utilizes a bridge current sensing loop that senses the output current and enables the very fast transient response of the device. This closed loop current sensing ensures the constant voltage output and very fast transient response of the device. The current sensing feature also helps to reduce the amount of energy dissipated on the output and helps to reduce the need for system overheating protection.

The device offers a wide input voltage range (1.8-5.5V) and high output voltage accuracy (±1%). It also offers adjustable current limit and soft start circuit, built-in voltage reference, over-temperature protection, reverse battery protection, and short circuit protection features. The device offers a very fast transient response and is capable of handling high current demands with minimal dropout and no significant noise. The device also includes an integrated voltage reference and PMOS pass device.
