ST890CDR

STMicroelectronics · AC-DC Controllers and Regulators · SOIC-8

ST890CDR from STMicroelectronics, in a SOIC-8. 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 IN power_in Input P-channel MOSFET source. Supply input, 2.7 V to 5.5 V. Bypass IN with a 1 µF capacitor to ground. Tied together with pin 2.
2 IN power_in Input P-channel MOSFET source. Supply input, 2.7 V to 5.5 V. Bypass IN with a 1 µF capacitor to ground. Tied together with pin 1.
3 ON input Active-low switch enable input (ON#). A logic low turns the P-channel switch ON; logic high turns it OFF. VIL max 0.8 V; VIH min 2.0 V at VI = 2.7-3.6 V, 2.4 V at VI = 2.7-5.5 V.
4 GND power_in Device ground reference.
5 SET input Current-limit programming input. Resistor RSET from SET to GND programs the output current limit ILIM. VSET ≈ 1.24 V reference; ILIM/ISET ≈ 1110; RSET = 1.24 × 1110 / ILIM. Maximum programmable ILIM = 1.2 A.
6 OUT power_out Switched output (P-channel MOSFET drain). Bypass OUT with a 0.1 µF capacitor to ground. Tied together with pin 7. 90 mΩ (typ.) ON-resistance at VI = 3 V.
7 OUT power_out Switched output (P-channel MOSFET drain). Bypass OUT with a 0.1 µF capacitor to ground. Tied together with pin 6.
8 FAULT output Active-low open-drain fault indicator (FAULT#). Pulled low when output current reaches ILIM, when a short-circuit event occurs, or when the die temperature exceeds ~135 °C (thermal shutdown 130 °C typ.). Requires an external pull-up resistor.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
st890cdr.step 122 KB You want the bare part, or you mark your own boards.
st890cdr-etched.step 2.1 MB You want the part with ST890CDR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 508 faces against 147 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: STMicroelectronics datasheet (19 pp, sha256 d156a463fe4876e7, 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).
