Linear Voltage Regulators (LVR) are electronic components made of one or more transistors that can convert an incoming direct current (DC) voltage source into a different, lower DC voltage source. The Texas Instruments TPS7A8500ARGRR is an example of an LVR which is designed for high performance applications in medical, industrial, and computer products. This article will discuss the application field of the TPS7A8500ARGRR, and its working principle.
The Application Field of TPS7A8500ARGRR
The TPS7A8500ARGRR is a high-performance, low-noise linear voltage regulator with a 2.7V to 13.2V output voltage range. The regulator is capable of providing up to 10A of continuous current and a maximum of 35A surge current. It is also able to withstand up to 15V overvoltage and is UL recognized. This makes it an ideal choice for a wide range of applications, such as medical and industrial equipment, automotive electronics, embedded control, and computer systems.
The TPS7A8500ARGRR has a wide operating temperature range from -40°C to +125°C and is ESD-protected for extremely robust operation. With its wide input voltage range, low output noise and ripple, excellent output accuracy, fast transient response, and high efficiency, the TPS7A8500ARGRR is ideal for powering almost any type of electronic device.
The Working Principle of TPS7A8500ARGRR
The working principle of the TPS7A8500ARGRR is based on the principle of feedback control. It uses a Philips control loop to control the output voltage. The device is made up of two main components - the input buffer, and the error amplifier. The input buffer amplifies the incoming voltage to a level suitable for the error amplifier. The error amplifier then compares the reference voltage to the output and adjusts the current flow through the pass transistor to maintain the desired output.
The error amplifier is designed to correct any difference between the reference voltage and the output, and adjusts the current flow through the pass transistor accordingly. If the output voltage is too low, the error amplifier will increase the current flow and bring the output voltage back up to the reference voltage. If the output voltage is too high, the error amplifier will reduce the current flow to bring the output voltage back to the reference voltage.
The TPS7A8500ARGRR also has a number of protection features, including overcurrent protection, undervoltage lockout, overvoltage protection, overtemperature shutdown and overvoltage foldback. The device also includes several output options, including a 25Mhz / 5V buffered output and a 0-5V buffered output.
In conclusion, the TPS7A8500ARGRR is a high performance, low noise linear voltage regulator that is suitable for a wide range of applications. It uses a Philips control loop to control its output voltage and features a wide operating temperature range, excellent output accuracy, and multiple protection features. Furthermore, it can provide up to 10A of continuous current and a maximum of 35A surge current.
