Frequently Asked Questions
What is the LM2575N-5.0 and what does it do?
The LM2575N-5.0 is a monolithic integrated circuit from Texas Instruments that provides all the active functions for a step-down (buck) switching regulator. It delivers a fixed 5V regulated output at up to 1A load current from an input supply ranging from 7V to 40V, operating at an internal 52kHz switching frequency with only 4 external components required.
What package and pin count does the LM2575N-5.0 use?
The LM2575N-5.0 comes in an 8-pin DIP (Dual In-line Package) through-hole package. The 8-DIP package measures 9.27mm x 6.35mm and is suited for breadboard prototyping or through-hole PCB assembly. The functional pins are: VIN (pin 1), OUTPUT (pin 2), GND (pin 3), FEEDBACK (pin 4), and ON/OFF (pin 5).
What is the operating temperature range of the LM2575N-5.0?
The LM2575N-5.0 is rated for an industrial temperature range of -40°C to +125°C, making it suitable for demanding environments including automotive support electronics, outdoor industrial equipment, and any application exposed to wide ambient temperature swings.
What are the best alternatives to the LM2575N-5.0?
Compatible alternatives include the LM2575HVN-5.0 (higher 60V input version), the LM2596N-5.0 (3A output, same fixed 5V), and the MC34063A (lower current, multi-topology). For a modern SMD replacement consider the TPS54331 or LMR14030 which offer higher efficiency and smaller footprint.
How do I order the LM2575N-5.0 and what is the minimum order quantity?
The LM2575N-5.0 is available to order with a minimum order quantity (MOQ) of 500 units. Volume pricing starts at $1.25/unit (500+), $1.18/unit (1000+), and $1.11/unit (10,000+).
