Frequently Asked Questions
What is the input voltage range of the LM2575T-5.0/NOPB?
The LM2575T-5.0/NOPB accepts an input voltage from 7V to 40V. It requires at least 2V headroom above the fixed 5V output, so a minimum input of 7V is recommended for proper regulation under full 1A load.
What output current can the LM2575T-5.0/NOPB deliver?
The LM2575T-5.0/NOPB is rated for a continuous output current of 1A. It also features internal current limiting and thermal shutdown protection to prevent damage under overload or short-circuit conditions.
What external components are needed for a typical LM2575T-5.0/NOPB circuit?
A typical application requires a catch diode (e.g., 1N5822 Schottky), an inductor (68–100µH), and input/output filter capacitors (100µF each). The fixed 5V output eliminates the need for feedback resistors, keeping the design simple.
Can the LM2575T-5.0/NOPB be used in automotive applications?
Yes, the LM2575T-5.0/NOPB can be used in automotive systems. With a 40V maximum input rating it handles typical 12V and 24V automotive battery voltages, including load-dump transients when proper clamping is applied upstream.
What are common alternatives to the LM2575T-5.0/NOPB?
Common alternatives include the LM2576T-5.0 (3A, same pinout), LM2596T-5.0 (3A, higher frequency), and the TPS54331 for a smaller SMD solution. For a pin-compatible replacement with higher efficiency, consider the TPS7560 or LM25575.
