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 | Positive input supply for the LM2596 step-down switching regulator. Absolute max 45V, recommended operating up to 40V. Requires a suitable input bypass capacitor (e.g. 470uF, 50V aluminum electrolytic) placed close to the pin to minimize voltage transients and supply the switching currents. |+| 2 | VOUT | output | Emitter of the internal NPN power switch; connects to the external inductor and catch diode of the buck converter. Saturation voltage Vsat is typically 1.16V at 3.0A. PCB area on this node should be kept small to minimize coupling to sensitive circuitry. |+| 3 | GND | power_in | Circuit ground pin. Use ground plane construction or single-point grounding for best regulation and noise performance. |+| 4 | FEEDBACK | input | Senses the regulated output voltage to close the feedback loop. On the fixed 5.0V version this pin ties directly to Vout; the internal resistor divider sets the 5.0V regulation point (Vref = 1.23V internal reference). Feedback bias current is typically 12 nA. |+| 5 | ON/OFF | input | Active-high shutdown input. Threshold is typically 1.3V; VIH >= 2.0V shuts the regulator OFF (dropping IQ to ~80uA typ, 200uA max), VIL <= 0.6V or floating leaves the regulator ON. Absolute input range is -0.3V to +VIN. Input current is ~5uA at 2.5V (OFF), ~0.02uA at 0.5V (ON). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HTC Korea TAEJIN Tech LM2596R 5 0 |+| Package | TO-263-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `LM2596R-5.0`+- `LM2596R-5.0LM2596R-ADJ`+- `LM2596R-5.0LM2596T-5.0`+- `LM2596R-5.0LM2596T-ADJ`+- `LM2596R-5.0LM2596DP-ADJ`++## CAD (KiCad official)++- Symbol: `LM2596R-5.0`+- Footprint: `Package_TO_SOT_SMD:TO-263-2`+- 3D model: TO-263-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HTC Korea TAEJIN Tech LM2596R 5 0 datasheet](docs/lm2596r-5-0-datasheet.pdf) (8 pp, sha256 `c89f43dda8481acd`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
