LR8323B-T50

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

LR8323B-T50 from LR, in a SOT-23-5L. 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 Input supply pin. Accepts 5.0V+dropout up to 24V (32V absolute max). Requires ≥1µF ceramic bypass capacitor close to the pin.
2 GND power_in Device ground reference. All voltages are referenced to this pin.
3 CE input Chip Enable (active-high ON/OFF control). Drive high to enable the regulator, drive low (VCE=0V) to shut down (shutdown current ISHD ≤1µA). Do not leave floating.
4 NC unconnected No internal connection. Leave floating or tie to GND per PCB convenience.
5 VOUT power_out Regulated 5.0V output (T50 suffix). Delivers up to 300mA typical (450mA current limit). Requires ≥1µF ceramic output capacitor for stability and transient response.

Two STEP files. Same geometry, different body top:

File Size Use it when
lr8323b-t50.step 85 KB You want the bare part, or you mark your own boards.
lr8323b-t50-etched.step 2.4 MB You want the part with LR8323B-T50 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 563 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: LR datasheet (11 pp, sha256 e63af50334fdca60, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • 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).
