S7819BS application field and working principleS7819BS is a kind of integrated circuit (IC) developed by SANYO Co., Ltd. It is an ultra low-power voltage regulator designed for portable and embedded devices. As it comes with a low power-saving shutdown mode, it can extend the operation time of batteries. It is widely used in smart phones, PDAs, digital cameras, audio players, toys, medical products and other portable and embedded devices.Working principleS7819BS IC is connected to two adjustable pins. One of the pins is the input voltage pin and the other is the output voltage pin. The two pins are connected to the power supply and the voltage regulator to be regulated, respectively. The input pin is connected to the power source. The output pin is connected to the voltage regulator to be regulated.When the voltage regulator starts to regulate the voltage, it will adjust the voltage through the voltage adjusting IC, S7819BS, by changing the supply voltage. This process is called voltage regulation. Through this process, it can provide a stable and regulated voltage to the electronic components connected to it. By adjusting the input voltage, it can provide voltage in various voltage range from 2.5V to 6.0V.Application FieldThe integrated circuit S7819BS has diverse application fields in various consumer electronics. It finds considerable application in cellular phones. For such electronic products, S7819BS can provide the low power shutdown mode for extending the operation time of the battery. Smartphones and media players also include S7819BS for providing stable voltage to the components in order to ensure the proper functioning of the device.Moreover, S7819BS has other applications other than providing low power shutdown mode. Due to its adjustable features, it also finds application in the regulated power supplies. This can be observed in medical equipments and toys, in which a steady source of voltage is essential for proper functioning. Moreover, it also finds application in flashlights, digital cameras, audio players, MP3 players etc.Finally, S7819BS has applications in the industrial sector as well. It can work as automation tools by providing voltage regulation between the Voltage Source (Boiler) and the Load Voltage (Generator). Moreover, S7819BS can be used for controlling the motor drives and providing power supply to solar energy systems.ConclusionS7819BS IC is an ultra low-power voltage regulator which is widely used in portable and embedded devices. It is used in mobile phones, PDAs, digital cameras, audio players, toys, medical equipments, regulated power supplies etc. for providing stable voltage to the electronic components. Apart from this, it is also used in the industrial sector in solar energy systems, motor drives and automation tools.
