Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VIN | power_in | Unregulated DC input supply to the regulator; operating supply voltage range is up to 40V (Operating Ratings) with an absolute maximum of 45V for the LM2575, and a minimum 47µF electrolytic bypass capacitor located near this pin and the ground pin is required for stable operation. |+| 2 | OUTPUT | output | Internal power-switch output pin that drives the external catch diode/inductor network; provides cycle-by-cycle current limiting with a 2.2A typical (1.7A-3.0A limit range) peak switch current, 0.9V typical (1.2V/1.4V max) saturation voltage at 1A, and a steady-state output-to-ground voltage limited to −1V minimum per the Absolute Maximum Ratings. |+| 3 | GND | power_in | Power ground return pin providing the common low-impedance ground reference for the regulator; for the equivalent 5-lead TO-220 package the datasheet states this pin and the package tab are both ground and part of the same copper lead frame, so either connection may be used. |+| 4 | FEEDBACK | input | Feedback input to the internal error amplifier; for the Adjustable version it must be connected to the external R1/R2 resistor divider (R1 between 1kΩ and 5kΩ) that sets VOUT, referenced to a 1.230V typical feedback voltage (1.180V-1.286V over line/load/temperature limits) with 50nA typical (up to 500nA max) bias current, and should be routed with short traces located near the regulator to avoid noise pickup. |+| 5 | ON/OFF | input | TTL/CMOS-compatible shutdown control input; ground or drive low (typically below 1.6V, VIL max 1.0V/0.8V) for normal ON operation, or drive high (VIH min 1.4V/2.2V-2.4V) to place the device in low-power standby mode drawing 50µA typical (200µA/500µA max) standby quiescent current; this pin can be pulled up to +VIN without a series resistor and must not be left floating. |+| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TO-263-5 |+| Category | Power Management (PMIC) |+| Pins | 6 |++## CAD (KiCad official)++- Symbol: `LM2575SX-ADJ`+- Footprint: `Package_TO_SOT_SMD:TO-263-5_TabPin6`+- 3D model: TO-263-5 (KiCad packages3D, STEP)+- 3D model files: `lm2575sx-adj-etched.step` / `lm2575sx-adj-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lm2575sx-adj.step` / `lm2575sx-adj.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/lm2575hv) (46 pp, sha256 `67d18983ac3edb34`, retrieved 2026-09-23, tier: lcsc)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.2`, primary `claude-haiku-4-5-20251001` (text), consensus `claude-sonnet-5` (agreed), guards: pin_guards 0.1: passed.
