Output voltage 9V
Linear voltage regulator kit - 5V-24V TO220 - 14pcs
Set of 14 popular stabilizers in TO220 enclosure.Linear voltage regulator 9V L7809CV - THT TO220
Stabilizer used to supply logic systems supplied with 9 V. The maximum output current is 1 A.What is a voltage stabilizer? How does it work and what is it for?
Voltage stabilizers are electronic systems that perform a protective function. The main task of any voltage stabilizer is to modulate the voltage in such a way as to maintain a constant voltage or current at the output of the system. The important thing is that the stabilizer is supposed to provide stable output values regardless of the input conditions.
DC voltage stabilizers are by far the most popular, but there are also stabilizers designed for alternating current. Current stabilizers are built on the basis of voltage stabilizers. For this purpose, negative feedback circuits are used. It then compares the output voltage with the pattern of the voltage source. In this way, a control signal is generated which influences the regulating element in such a way as to counteract the voltage variation at the output. In this way, we can obtain - in this case - an output voltage of 9 V.
The development of voltage stabilizers and the technological changes
Chronologically, at the very beginning, voltage stabilizers were primarily used to linearly stabilize discrete elements. Such parts include devices such as Zener diodes, transistors and lamps. Later, however, along with the technological development, these elements were replaced by high-tech integrated circuits with much better technical parameters.
Currently manufactured stabilizers in the form of integrated circuits are so advanced that virtually every device has built-in protection against overload or overheating. Thanks to these functionalities, the entire circuit - any equipment connected directly to the stabilizer circuit - is practically completely safe. Any overloads are immediately eliminated.
The vast majority of stabilizers are constructed in the form of three-terminal circuits. Over time, expensive metal housings have been replaced with cheaper, plastic ones. The 9 V output voltage is one of the possible configurations of a given system - in other subcategories of the Botland electronics store you will find voltage stabilizers in other versions: 1.8V, 8V, 10V, 12V and many others.
The most important parameters of voltage stabilizers
The main purpose of a voltage stabilizer is to provide a given system with a stable DC voltage (however, there are also devices dedicated to AC voltage). The stability of the voltage means that its value does not change. Regardless of external factors such as temperature, time, current, voltage will always be constant, and therefore safe.
Voltage stabilizers are very essential to programmable electronics, automation, machine programming and robotics. This is because the integrated circuits used in the above fields do not like alternating voltage. Often it can lead to errors or even damage to a particular hardware component. That is why integrated circuits that guarantee the supply of only a stable, constant voltage to electrical devices are so important.
When choosing a voltage stabilizer, first of all, you need to check the target devices for volt information. Another parameter is the voltage stabilization factor - each stabilizer can have a slightly different value of this factor. This factor is easy to calculate: it is the ratio of the change in the output voltage to the input voltage. A good quality stabilizer will have a low coefficient. Energy efficiency and efficiency are other important parameters.
