The UA-7805C Texas 220 5-volt 5-amp Voltage Regulator is a high-quality, linear voltage regulator that is designed to provide a stable and regulated 5-volt output. This regulator is ideal for use in various electronic applications, such as power supplies, digital logic circuits, and other voltage-sensitive devices.
The UA-7805C is a 3-terminal regulator, which means it has an input (VIN), output (VOUT), and ground (GND) terminal. The input voltage range for this regulator is 7 to 35 volts, making it suitable for use with a wide range of power sources. The regulator is capable of delivering a maximum output current of 5 amps, which is more than enough to power most low-power electronic devices.
One of the standout features of this regulator is its excellent regulation characteristics. The UA-7805C has a typical output voltage tolerance of 2% and a maximum output voltage deviation of 5%, which ensures that the output voltage remains stable even under load changes or input voltage fluctuations. This makes it an excellent choice for applications where precise voltage regulation is critical.
The UA-7805C is also known for its high efficiency. It has a typical dropout voltage of 2.5 volts at no load, which means that it can continue to deliver a regulated output even when the input voltage drops below the desired 5 volts. This can help to reduce power consumption and improve the overall efficiency of the system.
In terms of physical dimensions, the UA-7805C is a small, compact device that measures 17.5mm x 14mm x 7.4mm. It is available in a TO-220 package, which is a common and widely used package for linear voltage regulators. This makes it easy to integrate into most electronic circuits.
Overall, the UA-7805C Texas 220 5-volt 5-amp Voltage Regulator is a high-performance, reliable, and versatile voltage regulator that is well-suited for use in a wide range of electronic applications. Its excellent regulation characteristics, high efficiency, and compact size make it a great choice for designers and engineers looking for a high-quality voltage regulator solution.
