LT1963AEST-1.5#TRPBF

Introduction to LT1963AEST-1.5#TRPBF

The LT1963AEST-1.5#TRPBF is a low-dropout linear voltage regulator which is capable of regulating an output voltage of up to 1.5V with a dropout of only 200 mV. This regulator is capable of providing a continuous output current of up to 2 A and is ideal for use in applications with a wide input range and limited power available.

Application Field

The LT1963AEST-1.5#TRPBF is designed for use in a variety of applications, such as portable and hand-held devices, battery-powered electronics, automotive and industrial applications, and other applications with limited power available. As the device has a wide input range, it is ideal for a number of applications requiring a fixed voltage and current regulation.

Working Principle

The LT1963AEST-1.5#TRPBF is designed to regulate an input voltage of up to 28V and is capable of providing a continuous current of up to 2 A. It operates using a constant current sink, using a pass transistor to drop the excess voltage. The regulator compares the output voltage across an external resistor divider to an internal 1.25V reference. Any difference is regulated by switching current from the pass transistor at a rate proportionate to the difference between the reference voltage and the output of the resistor divider. This ensures accurate regulation with very low-dropout voltage.

Conclusion

The LT1963AEST-1.5#TRPBF is a low-dropout linear voltage regulator capable of providing up to 2 A of current with a maximum dropout of 200 mV. As it can take an input voltage of up to 28V, it is suitable for many applications where a regulated voltage is required, such as battery-powered electronics, automotive and industrial applications, and other applications with limited power available. The device is regulated using a constant current-sink principle, where the regulator switches current to the pass transistor to maintain a set voltage across the external resistor divider. This ensures accurate and stable regulation with very low-dropout voltage.
