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 | PGND | power_in | Power ground terminal; connect to system ground and AGND, and to the bypass capacitor with short wide traces. |+| 2 | VIN | power_in | Input supply to the regulator; connect a high-quality bypass capacitor or capacitors directly to this pin and PGND. |+| 3 | EN | input | Enable input to the regulator; high = ON, low = OFF, can be connected directly to VIN, must not be left floating. |+| 4 | PG | output | Open-drain power-good flag output; connect to a suitable voltage supply through a current-limiting resistor, high = power OK, low = power bad, pulls low when EN is low, can be left open when not used. |+| 5 | FB | input | Feedback input to the regulator; connect to the tap point of the feedback voltage divider, must not be left floating or grounded. |+| 6 | VCC | power_out | Internal 5-V LDO output used as supply to internal control circuits; do not connect to external loads other than the power-good pull-up, connect a high-quality 1-µF capacitor from this pin to GND. |+| 7 | BOOT | power_in | Bootstrap supply voltage for the internal high-side driver; connect a high-quality 100-nF capacitor from this pin to the SW pin. |+| 8 | SW | power_out | Regulator switch node; connect to the power inductor. |+| 9 | AGND | power_in | Analog ground for the regulator and system, ground reference for internal references and logic; on the HSOIC package the bottom thermal pad serves as both the AGND connection and a thermal connection to the heat-sink ground plane and must be soldered to a ground plane for good electrical and thermal performance. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8-EP |+| Category | Power Management (PMIC) |+| Pins | 9 |++## CAD (KiCad official)++- Symbol: `LMR33630BDDAR`+- Footprint: `Package_SO:SOIC-8-1EP_3.9x4.9mm_P1.27mm_EP2.29x3mm`+- 3D model: SOIC-8-EP (KiCad packages3D, STEP)+- 3D model files: `lmr33630bddar-etched.step` / `lmr33630bddar-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lmr33630bddar.step` / `lmr33630bddar.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/lmr33630) (57 pp, sha256 `71bca20c1f8dd624`, retrieved 2026-09-22, tier: lcsc)+- **Datasheet language:** Chinese.
