- Wide input voltage range from 6.5V to 29V (absolute max 25V continuous) in a through-hole compatible D2PAK package for high-current power supply designs
- Pb-free and RoHS compliant construction with built-in current limiting and thermal shutdown protection for reliable, robust power management
Applications
The LM1085ISX-5.0/NOPB is commonly used in post-regulator and point-of-load power supply designs where a stable 5V rail must be derived from higher-voltage sources such as 12V or 24V bus rails in industrial equipment, embedded systems, and test instruments. Its 3A current rating makes it suitable for powering logic boards, FPGAs, microcontrollers, and analog circuits that draw significant current. The device is also used in battery-powered systems, automotive accessories, and benchtop power supply modules requiring a fixed 5V output.

Frequently Asked Questions
What is the output voltage and maximum current of the LM1085ISX-5.0/NOPB?
The LM1085ISX-5.0/NOPB provides a fixed 5.0V output at up to 3A of continuous output current, making it suitable for powering multiple digital and analog loads simultaneously from a single regulator.
What is the dropout voltage of the LM1085ISX-5.0/NOPB?
The LM1085ISX-5.0/NOPB has a nominal dropout voltage of 1.3V and a maximum of 1.5V at full load, meaning the input supply must be at least 6.5V to maintain regulation, which is considerably lower than standard LDO alternatives.
What is the maximum input voltage for the LM1085ISX-5.0/NOPB?
The LM1085ISX-5.0/NOPB accepts a maximum continuous input voltage of 29V (absolute maximum 25V for the specified operating range), making it suitable for use with 12V, 15V, and 24V power buses commonly found in industrial and embedded systems.
What package does the LM1085ISX-5.0/NOPB use and how is it mounted?
The LM1085ISX-5.0/NOPB is housed in a 3-pin D2PAK (TO-263) surface-mount package, which provides excellent thermal performance due to its large exposed pad and is suitable for high-current surface-mount applications on standard FR4 PCBs.
Does the LM1085ISX-5.0/NOPB include overcurrent and thermal protection?
Yes, the LM1085ISX-5.0/NOPB includes internal current limiting and thermal shutdown protection circuits that automatically protect the device and the load from damage under fault conditions such as overloads and short circuits.
