：S-817A12APF-CUBTFU is a low dropout (LDO) linear voltage regulator from Shenzhen Jiexiang Technology Co., Ltd. It has a wide application field and working principle.
Application Field
This product can be used in a variety of applications, such as cell phones, computers, digital cameras, digital music players, game consoles, digital TVs, card machines, industrial control equipment, routers and satellite receivers.
It is widely used in special low-power applications, such as automotive electronics systems and other applications that require very low power consumption, since it has the additional advantage of being stable and resistant to fluctuations in the input power.
In addition, it is also used for high-performance and reliable power supply, because it can provide a constant output voltage with a very low quiescent current.
Working Principle
The S-817A12APF-CUBTFU is a linear voltage regulator, which converts a higher input voltage to a constant lower output voltage. It works by taking a voltage from a higher voltage source and regulating it to a lower voltage with a pass transistor.
The device features an adjustable current-limiting, thermal shut down and short-circuit protection. It has an additional output terminal to monitor and limit the output current.
The device utilizes a bipolar transistor as a pass element and a zener diode and a resistor to achieve the desired output voltage limitation.
The bipolar transistor is used as a pass element because it has a low voltage drop and low power dissipation, meaning it can produce a smaller output voltage drop than other linear devices, such as FETs.
The zener diode is used to protect the output voltage from exceeding the maximum safe limit and the resistor controls the amount of current delivered to the output.
The device also utilizes an additional terminal to sense the output voltage, allowing it to react to even the smallest voltage changes.
In addition, the device can be configured to provide a fixed output voltage, or to provide a variable output voltage with an external adjustable pin.
The S-817A12APF-CUBTFU is a versatile linear voltage regulator and is ideal for a wide range of applications. Its high performance and reliability make it a great choice for all your power needs.
