Working Principle of LT1963AEFE#TRPBF

The LT1963AEFE#TRPBF is a low dropout linear regulator that operates over a wide input voltage range (2V–10V) and output voltage range (0.6V–5V) capabilities. The linear regulator uses a PNP pass transistor to regulate the output voltage through a feedback network. As the load current increases, the pass transistor increases its current and the voltage across it will increase accordingly. This voltage is then compared to the reference voltage through an error amplifier that synthesizes the output to the required level.

The LT1963AEFE#TRPBF has an integrated high current output, which can be configured to provide up to 2A of current with a maximum dropout voltage of 30mV at full current load. The device uses a precision voltage reference with a tolerance of 2%. This ensures accurate and repeatable output voltage. The output voltage is further ensured by a two-level built-in overtemperature protection (OTP) circuit. In addition, the device offers a wide range of features including adjustable current limit, output tracking, overvoltage protection, and soft start.

The LT1963AEFE#TRPBF is designed to operate with minimal external components, making it an attractive option for high-performance power regulation and management applications. The device is offered in an array of packages including standard, lead-free and RoHS compliant versions, giving designers the freedom to select the optimal solution for their application.

Conclusion

The LT1963AEFE#TRPBF is a flexible, low-dropout linear regulator that fits a variety of applications. Its wide operating range, high current output, low dropout voltage, and various features make it ideal for power systems requiring tight regulation over a wide input voltage range.
