SY8008BAAC

Silergy Corp · DC-DC Converters · SOT-23-5

SY8008BAAC from Silergy Corp, in a SOT-23-5. 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 (>1.5V) to turn on the regulator; pull below 0.4V to disable. Must not be left floating; a 1MΩ pull-down to GND is recommended when driven from a high-impedance source connected to a battery rail.
2 GND power_in Ground return pin. Also serves as the case position for θJC thermal measurement; maximize PCB copper area for best thermal and noise performance.
3 LX output Switching node output. Connect to the external inductor. Minimize PCB copper area on this net to reduce radiated noise; do not route the FB trace adjacent to this net.
4 IN power_in Supply input pin, 2.5V to 5.5V operating range (6.0V absolute max). Decouple to GND with at least a 1µF (X7R, ≥4.7µF recommended, ≥6V rated) ceramic capacitor placed close to the IN/GND pins.
5 FB input Output voltage feedback pin. Connect to the center point of an external resistor divider from VOUT to program the output: Vout = 0.6V × (1 + R1/R2). Internal reference is 0.6V (±2%). An optional 10-47pF feed-forward cap across R1 speeds up the transient response.

CAD (KiCad official)

  • Symbol: SY8008BAAC
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: sy8008baac-etched.step / sy8008baac-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sy8008baac.step / sy8008baac.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sy8008baac.step 85 KB You want the bare part, or you mark your own boards.
sy8008baac-etched.step 2.3 MB You want the part with SY8008BAAC already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 545 faces against 102 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Silergy Corp datasheet (9 pp, sha256 011a668c9a0b98b6, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
