The Texas Instruments LM1084IS-5.0/NOPB is a robust 5A low dropout linear regulator providing a fixed 5.0V output. Its 1.5V maximum dropout at full load and 68dB ripple rejection make it ideal for post-regulation and noise-sensitive applications. Housed in a TO-263 package, it offers excellent thermal performance for demanding industrial and automotive environments.
- High 5A Output Current: Supports power-hungry digital loads without external pass transistors, simplifying design.
- Low Dropout (1.5V @ 5A): Maintains regulation with minimal input-to-output headroom, improving efficiency in battery systems.
- Excellent PSRR (68dB @ 120Hz): Effectively filters mains-frequency ripple, ideal for clean analog supplies.
- Thermally Efficient TO-263 Package: Dissipates heat effectively, ensuring reliable operation at maximum current.
High-Current 5V Logic Rails
Power FPGAs, ASICs, and digital processors requiring a clean, regulated 5V supply at up to 5A. The low dropout and high current capability ensure stable operation under transient loads.
Post-Regulation for Switching Supplies
Use after a DC-DC converter to eliminate switching noise. The 68dB PSRR at 120Hz effectively attenuates ripple, providing a quiet analog supply.
Battery-Powered Industrial Equipment
With a 1.5V dropout, it efficiently regulates from a 6.5V battery down to 5V, extending usable battery life in portable industrial tools.
5V Audio and Precision Analog Circuits
Deliver low-noise 5V power to op-amps, DACs, and ADCs. The high PSRR and stable output minimize power-supply-induced distortion.
Automotive Infotainment Systems
Regulate vehicle battery voltage (12V nominal) down to 5V for infotainment processors, with robust thermal performance in the TO-263 package.
Networking and Telecom Line Cards
Provide a dedicated 5A, 5V rail for high-speed transceivers and line drivers, ensuring reliable data transmission with minimal voltage sag.
