LR8323B-T18

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

LR8323B-T18 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 Unregulated input supply. Operating input range up to 24V (absolute max 32V). Bypass to GND with a ≥1uF ceramic capacitor placed close to the pin to ensure stability and good transient response.
2 GND power_in Device ground reference and return for input/output capacitors. All voltages in the electrical characteristics table are referenced to this pin.
3 CE input Chip Enable (ON/OFF) input. Drive high to enable the regulator; drive to 0V (VCE=0V) to enter shutdown mode where ISHD ≈ ±1uA. Do not leave floating.
4 NC unconnected No internal connection. May be left floating or tied to GND; do not use as a routing via.
5 VOUT power_out Regulated output, fixed 1.8V (T18 suffix). Delivers up to 300mA typical; OCP kicks in at ~450mA and short-circuit current is clamped to ~20mA when VOUT<0.7V. Requires a ≥1uF ceramic output capacitor to GND for stability and load-transient response.

CAD (KiCad official)

  • Symbol: LR8323B-T18
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5L (KiCad packages3D, STEP)
  • 3D model files: lr8323b-t18-etched.step / lr8323b-t18-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lr8323b-t18.step / lr8323b-t18.glb are the bare package body.

Provenance

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

  • Datasheet: LR datasheet (11 pp, sha256 19e3748c68fb39fe, 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).
