Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | SW_PG | output | Active-high power-good output for the switch, a CMOS logic-level signal with no external pullup required that is pulled low when SW_OUT falls below 88% of 5 V for the TPS2151. |+| 2 | SW_IN | power_in | Input of the integrated N-channel high-side power switch, which has a maximum on-state resistance of 65 mΩ and is rated for 500 mA continuous current. |+| 3 | SW_IN | power_in | Input of the integrated N-channel high-side power switch (second SW_IN pin, internally tied to pin 2), which has a maximum on-state resistance of 65 mΩ and is rated for 500 mA continuous current. |+| 4 | LDO_IN | power_in | Input of the internal adjustable LDO, which supports 2.7 V to 5.5 V VIN, has a 0.5 V maximum dropout and is rated for 250 mA continuous current. |+| 5 | SW_EN | input | Active-high enable for the switch on the TPS2151, with an internal pulldown (this pin is active low on the TPS2140/41). |+| 6 | LDO_EN | input | Active-high enable signal for the LDO regulator, with no internal pullup or pulldown. |+| 7 | GND | power_in | Ground reference for the device. |+| 8 | LDO_PG | output | Open-drain, active-high power-good signal for the LDO output. |+| 9 | ADJ | input | Feedback adjustment input of the LDO regulator used to set the output voltage over the 0.9 V to 3.3 V adjustable range. |+| 10 | LDO_PLDN | input | Output pulldown pin for the LDO, used when connected to LDO_OUT to discharge the output. |+| 11 | LDO_OUT | power_out | Output of the adjustable LDO regulator, which is rated for 250 mA continuous current. |+| 12 | SW_OUT | power_out | Output of the internal power-distribution switch, which applies dual current limiting during turn-on and overload. |+| 13 | SW_OUT | power_out | Output of the internal power-distribution switch (second SW_OUT pin, internally tied to pin 12), which applies dual current limiting during turn-on and overload. |+| 14 | SW_PLDN | output | Open-drain discharge pin for the switch that is open when the switch is on and pulled to ground otherwise; connecting it to SW_OUT reduces the output fall time. |+| 15 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | HTSSOP-14-EP |+| Category | Power Supply Chip |+| Pins | 15 |++## CAD (KiCad official)++- Symbol: `TPS2151IPWP`+- Footprint: `Package_SO:TSSOP-14-1EP_4.4x5mm_P0.65mm`+- 3D model: HTSSOP-14-EP (KiCad packages3D, STEP)+- 3D model files: `tps2151ipwp-etched.step` / `tps2151ipwp-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps2151ipwp.step` / `tps2151ipwp.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/tps2150) (33 pp, sha256 `8316b929dcdd03f1`, retrieved 2026-10-07, tier: lcsc)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.3`, primary `claude-haiku-5-5` (text), consensus `claude-sonnet-5-5` (agreed), guards: pin_guards 0.1: passed.
