Frequently Asked Questions

What is the output voltage and accuracy of the LD1086DT25?

The LD1086DT25 provides a fixed 2.5V output with ±1% accuracy, ensuring the regulated voltage stays between 2.475V and 2.525V across load and temperature variations, making it suitable for precision analog and digital circuits.

What is the maximum input voltage and dropout voltage of the LD1086DT25?

The LD1086DT25 accepts an input voltage up to 30V absolute maximum and has a nominal dropout voltage of 1.3V (maximum 1.5V at full load), so a minimum input of approximately 4.1V is needed to maintain regulation at 2.5V output.

What package does the LD1086DT25 come in and what are its thermal advantages?

The LD1086DT25 is housed in a 3-pin DPAK (TO-252) surface-mount package, which provides good thermal dissipation through the exposed pad, allowing the regulator to handle up to 1.5A continuous output current on standard PCB layouts with appropriate copper area.

What are typical applications for the LD1086DT25?

This regulator is widely used in embedded systems, industrial controllers, telecom equipment, and consumer electronics requiring a stable 2.5V supply for microcontrollers, DSPs, FPGAs, memory devices, and analog reference circuits where dropout voltage and output accuracy are critical.

Is the LD1086DT25 RoHS compliant?

Yes, the LD1086DT25 carries the JESD-609 code e3, indicating it is RoHS compliant and lead-free, making it suitable for modern eco-friendly manufacturing processes and export to markets requiring RoHS compliance.
