LM2576S-5.0
Texas InstrumentsLM2576S-5.0 is a Texas Instruments SIMPLE SWITCHER 3 A step-down regulator in TO-263 — for fixed 5 V rails in legacy and industrial designs: the original easy-to-use buck needing only 4 external components. Fixed 5.0 V output ±4%, up to 45 V input (63 V for HV version), 52 kHz fixed-frequency oscillator, TTL shutdown capability. Heat evidence: classic 5 V switchers hold firm pricing through analog upcycles — the LM2576 remains a go-to for maintenance builds where the original design is qualified. Selection advice: 52 kHz means a physically large inductor by modern standards — for new designs consider the synchronous LMR51430; for drop-in legacy 5 V rails the S (TO-263) package is the SMT choice. Parameters verified against Texas Instruments documentation.
