S-812C45AY-B2-U

The S-812C45AY-B2-U is a high-performance linear voltage regulator. Typical applications of the voltage regulator include industrial, computer, and automotive applications, amongst many others. Its general purpose design, combined with its low output noise, fast transient response, high power supply rejection ratio, and low dropout voltage make it suitable for a wide range of applications. Additionally, this regulator can be used in applications where short-circuit protection and over-temperature shut down are required.

The S-812C45AY-B2-U voltage regulator is a three-terminal adjustable linear regulator, which integrates a voltage reference, pass element, and current limiting on a monolithic chip. A regulated output voltage is obtained by connecting a resistor from the output pin to the adjust pin. The output voltage can be adjusted by connecting a resistor to reference ground and a second resistor to the adjustment pin. The ratio of these resistors sets the output voltage.

The S-812C45AY-B2-U has a built-in thermal shut-down protection circuitry which activates if the regulator\'s junction temperature exceeds a preset level. When triggered, the thermal shut-down protection will reduce the output current to prevent the chip from being damaged by excessive over-temperatures. The thermal shut-down protection can be re-enabled once the chip\'s junction temperature has dropped to a safe level.

The S-812C45AY-B2-U is designed to have a very low dropout voltage, which means that it can regulate accurately even when the input voltage is very close to the output voltage. This makes it ideal for applications where power dissipation is a major design concern or where there are special requirements for low power consumption.

The S-812C45AY-B2-U is typically used in applications such as switching power supplies, PWM motor controllers, automotive systems, handheld devices, and consumer electronics to provide a low-cost, adjustable, linear voltage regulator with low power consumption and high reliability. Its simple design and low cost make it one of the most popular linear voltage regulators currently available.

In summary, the S-812C45AY-B2-U voltage regulator is an ideal choice for a wide range of applications that require an adjustable, low power, and high-reliability voltage regulator. Its low dropout voltage, low noise, fast transient response, and high power supply rejection ratio make it suitable for a variety of applications. Its adjustable output voltage and over-temperature shut down protection make it an easy choice for designers looking for a reliable and cost-effective linear voltage regulator solution.
