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 | EN | input | Enable control input. Pull high (VIH ≥ 1.5V) to turn the IC on; pull low (VIL ≤ 0.4V) to disable the IC. Must not be left floating. |+| 2 | GND | power_in | Ground reference pin for the device. |+| 3 | LX | output | Power switching output. Connect an external inductor to the drains of the internal high-side PMOS and low-side NMOS. Switches between VIN and GND at ~1MHz. |+| 4 | VIN | power_in | Power supply input pin. Drive with 2.5V to 5.5V to power the chip. Bypass with a 10µF MLCC to GND close to the pin. |+| 5 | FB | input | Voltage feedback input. Connect FB to VOUT through a resistor divider; the IC regulates FB to the internal 0.6V reference (VREF = 0.588-0.612V). VOUT = 0.6V × (1 + R1/R2). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Shenzhen JingYang |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `TD8002ES5X`+- `TD8002ES5XES6`++## CAD (KiCad official)++- Symbol: `TD8002ES5X`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Shenzhen JingYang datasheet](docs/td8002es5x-datasheet.pdf) (15 pp, sha256 `b408d40883965a8c`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
