No adjustable version — the output voltage is set internally, so the BOM needs no feedback divider. The 52 kHz switching frequency is low by today's standards; it keeps the inductor physically larger than a 500 kHz design but reduces switching losses and radiated EMI. The 4.75 V to 40 V input range lets it regulate from a loosely regulated 5 V rail or a 24 V industrial bus without a pre-regulator. ## Through-hole TO-220-5 — board fit and thermal path The TO-220-5 package is a through-hole power package with a metal tab for heatsinking. The tab is the ground path and the primary thermal interface — a PCB copper pour under the tab or a bolt-on heatsink keeps the junction below 125°C at 1 A output. No synchronous rectifier means an external Schottky diode carries the catch current; pick one rated for the input voltage and 1 A average with margin. This covers industrial enclosures, outdoor telecom cabinets, and under-hood automotive-adjacent environments. The 125°C ceiling is the junction limit, not the ambient — derate the 1 A output according to the thermal resistance of the TO-220 tab-to-ambient path.","metaTitle":"TI TL2575-33IKV Buck Regulator, 3.3V Fixed, 1A, TO-220-5","metaDescription":"Active-production step-down buck regulator from Texas Instruments.
