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 | CE | input | Chip enable input. Drive high (>1.2 V typ) to enable normal switching operation; drive low (<0.4 V) to place the device in zero-current shutdown. Typical CE trigger level is 0.8 V with VDD = 3.3 V. |+| 2 | EXT | output | Gate/base drive output for an external power transistor (NMOS or NPN) used to extend output current beyond the internal switch capability. Maximum drive current is 200 mA; on-resistance is 4.4 Ω (EXT-to-VDD) and 2.45 Ω (EXT-to-GND) typ at VDD = 3.3 V. |+| 3 | GND | power_in | Device ground return. Connect to the system ground plane with a short, wide trace. |+| 4 | LX | output | Switching node driven by the internal NMOS power switch. Connect to the junction of the boost inductor and the rectifier diode. Absolute max VLX = 7 V; on-resistance to GND is 0.3 Ω typ; current limit is 1.5 A typ (peak inductor current rating 2.5 A). |+| 5 | VDD | power_in | IC supply input, sensed at the boosted output rail (bootstrapped operation). Operating range 2 V to 6 V; absolute max 7 V. Bypass to GND with a 1 µF MLCC using short, wide traces. |+| 6 | FB | input | Feedback input to the internal error amplifier. Reference voltage is 1.25 V typ (1.225-1.275 V). Set output voltage with a resistor divider from VOUT to GND using Vout = (1 + R1/R2) × 1.25 V; keep node copper small and away from noise sources. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | PowTech CR PowTech Shanghai |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++Same part, different packaging or reel option.++- `PT1301D23F`+- `PT1301D23FE89E`+- `PT1301D23FEMSH`++## CAD (KiCad official)++- Symbol: `PT1301D23F`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [PowTech CR PowTech Shanghai datasheet](docs/pt1301d23f-datasheet.pdf) (10 pp, sha256 `20ff3ed7476142e1`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
