SK7905U

Shikues · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252

SK7905U from Shikues, in a TO-252. 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 GND power_in Ground / common return pin. Reference for both the negative input and the negative output voltage. On the TO-252 package this is also the tab-adjacent pin.
2 VIN power_in Negative input supply pin. Accepts the unregulated negative rail; absolute maximum -35V. Recommended operating range for -5V output is approximately -7V to -25V. A 2.2 uF input capacitor to GND is recommended.
3 VOUT power_out Regulated negative output pin. Provides -5.0V (typ) at up to 1.5A with a dropout voltage of ~2V at 1A. A 1 uF output capacitor to GND is recommended for stability.

CAD (KiCad official)

  • Symbol: SK7905U
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252 (KiCad packages3D, STEP)
  • 3D model files: sk7905u-etched.step / sk7905u-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sk7905u.step / sk7905u.glb are the bare package body.

Provenance

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

  • Datasheet: Shikues datasheet (6 pp, sha256 0762a6e682b0350c, retrieved 2026-08-17, tier: lcsc)
  • 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).
