Working Principle

The SC1565IT-2.5T is a linear voltage regulator, meaning that it produces a regulated output voltage from an unregulated input voltage source. In this case, the input voltage is up to 50V and the output voltage is adjustable from 0.8V to 13.2V. The control loop of the device provides for a fast and accurate output voltage regulation.

The device works on the principle of a voltage divider. An internal resistor (R1) and an external resistor (R2) form a voltage-divider circuit, with the output of the voltage-divider being fed back to the Control pin (Ctrl) of the regulator. The output voltage is then adjusted to a voltage level determined by the ratio of the two resistors. The error amplifier continuously monitors the output and compares it to the reference voltage. If needed, the error amplifier will adjust the output voltage to ensure that it is at the correct voltage level.

The SC1565IT-2.5T also features a variety of protection features, such as current limiting and thermal shutdown, which keep the device safe from damage during extreme conditions. The thermal shutdown protection prevents the device from overheating, while the current limiting feature ensures that the device does not draw more than the maximum rated current.

Conclusion

The SC1565IT-2.5T is a linear voltage regulator from the PMIC – Voltage Regulators – Linear category. It can supply up to 2.5A of output current with an adjustable output voltage ranging from 0.8V to 13.2V. This device is ideal for a wide range of applications, including power converters, battery-powered applications, and automotive systems.
