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. Operating range 4.5V-40V (60V for HV variants). Bypass to GND with a large low-ESR capacitor placed close to the pin to suppress input ripple/noise. |+| 2 | OUTPUT | power_out | Internal power switch (emitter) output node. Connects to the external inductor / catch diode of the buck converter and swings between VIN and one diode-drop below ground at 150kHz. |+| 3 | GND | power_in | Circuit ground reference. Route the return path from the catch-diode/output-capacitor back to this pin with a short, low-inductance trace to avoid switching-noise pickup. |+| 4 | FEEDBACK | input | Regulator feedback sense input. Internal reference is 1.23V; on fixed-output versions such as the -5.0 the divider is integrated so this pin is tied directly to the output rail through an internal network. |+| 5 | ON_OFF | input | Active-low enable input. Logic-low (<0.8V) or floating enables the regulator; logic-high (>1.4V, up to VIN) shuts the part down. Standby current ~80uA when disabled. |+| 6 | NC | unconnected | No internal connection on SOP-8/ESOP-8 package. May be left floating or tied to GND. |+| 7 | NC | unconnected | No internal connection on SOP-8/ESOP-8 package. May be left floating or tied to GND. |+| 8 | NC | unconnected | No internal connection on SOP-8/ESOP-8 package. May be left floating or tied to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI LM2596ME 5 0 TR |+| Package | ESOP-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `LM2596ME-5.0/TR`+- `LM2596ME-5.0LM2596M-5.0/TR`+- `LM2596ME-5.0LM2596DQ4-5.0/TR`+- `LM2596ME-5.0LM2596T-5.0`+- `LM2596ME-5.0LM2596HVT-5.0`+- `LM2596ME-5.0LM2596S-5.0/TR`+- `LM2596ME-5.0LM2596HVS-5.0/TR`+- `LM2596ME-5.0LM2596MD5T-5.0/TR`+- `LM2596ME-5.0LM2596MDT-5.0/TR`+- `LM2596ME-5.0LM2596TB-5.0`+- `LM2596ME-5.0LM2596HVTB-5.0`++## CAD (KiCad official)++- Symbol: `LM2596ME-5.0`+- Footprint: `Package_SO:SOIC-8-1EP_3.9x4.9mm_P1.27mm_EP2.41x3.3mm`+- 3D model: ESOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HGSEMI LM2596ME 5 0 TR datasheet](docs/lm2596me-5-0-datasheet.pdf) (17 pp, sha256 `986b3081cc1a4676`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
