TPS7A8300ARGWT is an ultra-low-noise, low-dropout linear regulator designed to provide an adjustable regulated output voltage to supply sensitive analog loads in space-constrained applications. This device is the perfect choice for systems that require the lowest noise output and fast transient response.

The TPS7A8300ARGWT operates over a wide input voltage range of 1.5V to 6.0V and supports output voltages as low as 0.8V. Its output current of up to 200mA can be fine-tuned by using an external resistor divider. An adjustable soft-start feature helps reduce in-rush current upon power-up and its low-dropout voltage ensures the device will provide a regulated voltage to the load in the most demanding conditions.

The unique design of the TPS7A8300ARGWT enables it to provide exceptional noise performance for sensitive loads. Its excellent power-supply rejection ratio (PSRR) and zero-drift architecture make it perfect for precision analog systems. It also incorporates an advanced EMI noise filter that helps reduce EMI/RFI interference.

As a highly integrated device, the TPS7A8300ARGWT provides a complete power solution for applications such as medical test systems, measurement equipment, and communication systems. It eliminates the need to design and source multiple discrete power solutions, thus saving time and reducing component count and total cost.

To ensure the device is suitable for your application, there are various features such as overtemperature protection, high in-rush current limit and reverse current protection. In addition, the device has a wide operating temperature range of -40°C to +125°C and is available in compact, thermally enhanced surface-mount packages. With these features, the TPS7A8300ARGWT can easily meet the requirements of the most demanding applications.

The working principle of TPS7A8300ARGWT is based on a voltage regulator topology that employs an internal reference voltage to regulate the output voltage. A feedback circuit is used to detect and correct any output voltage variations. The reference voltage is created by an on-chip bandgap circuit. This bandgap voltage is used to compare the output voltage to the input voltage by a voltage comparator. When the output voltage deviates from the reference voltage, the comparator output is used to adjust the output voltage. The correction is done by controlling the amount of current passing through a series pass element(an internal MOSFET) which is connected to the output pin. When the current is larger, the output voltage will be higher and when it is smaller the output voltage will be lower. With this principle, the TPS7A8300ARGWT can maintain a tight tolerance on output voltage and provide excellent noise performance over a wide temperature range.
