PMIC - Voltage Regulators - Linear: SC1566IT-2.5T Application Field and Working Principle

The SC1566IT-2.5T is an adjustable linear voltage regulator designed by Supertex Inc. It is designed to provide a stable output voltage up to 2.5V across its temperature range of -40 °C to +125 °C. This device is ideal for use in lithium-ion batteries, automotive electronics, and industrial systems. Its maximum output current is 100mA and its output voltage can be adjusted from 0V to 2.5V with the use of an external resistor.

The SC1566IT-2.5T consists of an operational amplifier, an error amplifier, a voltage reference, and a series of transistors. The operational amplifier senses the output voltage and compares it to the reference voltage. Any difference between the two is then amplified by the error amplifier. This amplified difference is used to control the transistors, which regulate how much current is allowed to flow into the output. By adjusting the external resistor, the error amplifier’s difference signal can be adjusted so that the output voltage is set to the desired value.

The SC1566IT-2.5T can help reduce system power dissipation and improve longevity. Its thermal ratings of 125°C junction temperature and 150°C peak temperature are beneficial in applications that require extended operation in extreme temperature conditions. The device’s extremely low quiescent current draw of only 2uA is also advantageous in low-power designs.

The SC1566IT-2.5T has a number of applications in industrial and electronic systems. It can be used in systems requiring current limiting and over-temperature protection. It can also serve as a voltage reference for systems experiencing voltage perturbations, and its signal conditioning circuitry offers improved signal stability and noise reduction. Furthermore, the device is suitable for use in systems with high transient and cycle-by-cycle current demands, such as power management systems and motor control circuits.

The SC1566IT-2.5T is a highly reliable and accurate device. Its ripple rejection exceeds 70dB at 100kHz, and its operating temperature range allows for use in hostile temperature environments. In addition, the low output noise of only 25uV gives the device higher noise immunity than other devices in its category.

The SC1566IT-2.5T is an excellent choice for linear voltage regulation in industrial and electronic systems. Its high performance and extended temperature ratings make it suitable for a wide range of applications. Its low quiescent current draw and high ripple rejection make it an ideal choice for low-power and noise-sensitive designs. Finally, its signal conditioning circuitry and over-temperature protection features ensure improved signal stability, reliable protection, and enhanced system longevity.
