The S-812C34AY-Z2-U is a linear voltage regulator manufactured by Seiko Instruments. It is categorized under PMIC-Voltage Regulators-Linear, and is primarily used for providing a stable output voltage while suppressing noise, or step up and buck converter-type regulators. The S-812C34AY-Z2-U is capable of providing an output voltage range of 1.25V to 32V, with a current range of 0.3mA to 200mA. The input voltage range is 3V to 40V, and the device can operate in three different modes: low, mid and high power. The S-812C34AY-Z2-U also features a built-in thermal shut down circuit and an under voltage lockout circuit for protection against reverse input voltage.The linear voltage regulator is an essential component of any power supply, as it is used to maintain the output voltage at the rated level by controlling the amount of current drawn from the input power source. This is achieved by monitoring the input and output voltage and adjusting the amount of current through the regulating element. The prime advantage of a linear voltage regulator is that it does not produce any switching noise, and is also highly efficient.The S-812C34AY-Z2-U is essentially a low power linear voltage regulator. It has an output voltage range of 1.25 to 32V and can provide a current of up to 200mA. It comes with an adjustable current limiter switch which can be used to limit the current flow depending on the load.The S-812C34AY-Z2-U operates in three modes: Low, Mid and High power mode. In Low power mode, the device is able to provide a low current output of up to 0.3mA and has an internal thermal shut down. In Mid Power mode, it is capable of providing up to 2A of current with an under voltage lockout circuit. Lastly, the device can also operate in High Power mode, providing up to 20A of current.The S-812C34AY-Z2-U can be used in a variety of applications, such as power electronics, communication, instrumentation, home appliances, and industrial applications. For instance, it can be used in solar panel regulators, in motor controllers for controlling the speed of electric motors, and in DC-DC converters for obtaining an output voltage that is different from the input voltage. The working principle of a linear voltage regulator is based on the operation of a bipolar junction transistor known as pass element. The regulator has two inputs, viz. the input voltage, and the output voltage. The input voltage is monitored by the voltage regulator and the output voltage is controlled by the pass element.The pass element acts like a variable resistor, and is connected across the load. When the output voltage changes, the resistance of the pass element also changes, resulting in a change in the current passing through the load. As a consequence, the voltage at the output remains constant, while the current is regulated.The S-812C34AY-Z2-U is a highly versatile device, as it can be used in a variety of applications, including power supplies, DC-DC converters, solar panel regulators, and motor controllers. It features built-in protection features and its adjustable current limit switch ensures that the voltage regulator does not exceed its rated current.The S-812C34AY-Z2-U linear voltage regulator is a must-have device in any power supply setup, as it ensures that the output voltage remains at the rated level, while providing excellent noise suppression. This makes it ideal for a wide range of applications, ranging from home appliances to industrial applications.
