LN1134A332MR-G

NATLINEAR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

LN1134A332MR-G from NATLINEAR, 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 VIN power_in Regulator input supply. Operating range 2.0 V to 7 V (absolute max VSS-0.3 V to VSS+8 V). Requires ≥1.0 µF input decoupling capacitor (C1) to VSS.
2 VSS power_in Device ground / common return. Reference for VIN, VOUT, and CE thresholds.
3 CE input Chip Enable. Active-high on the 'A' variant with an internal pull-down resistor (device ON when CE ≥ 1.6 V, OFF when CE ≤ 0.25 V). Absolute max VSS-0.3 V to VSS+8 V (VON/OFF spec). Standby current <2 µA when disabled.
4 NC unconnected No internal connection on the SOT-23-5 package. Leave floating or tie to VSS for mechanical stability.
5 VOUT power_out Regulated 3.3 V output. Delivers up to 300 mA (VIN ≥ VOUT+1 V), ±2% initial accuracy, typical dropout 0.30 V at 100 mA. Requires ≥1.0 µF output capacitor (C2, tantalum or ceramic).

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ln1134a332mr-g.step 85 KB You want the bare part, or you mark your own boards.
ln1134a332mr-g-etched.step 2.3 MB You want the part with LN1134A332MR-G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 584 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: NATLINEAR datasheet (11 pp, sha256 6b5d04fe427c104a, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
