LR8323B-T12

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

LR8323B-T12 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. Absolute maximum 32V; recommended operating input up to 24V. Bypass to GND with at least 1uF ceramic capacitor (1uF-10uF typical); a small series resistor (~10Ω) is recommended to snub upstream spikes.
2 GND power_in Device ground reference. All voltages in the datasheet are referenced to GND. A large ground pour is recommended to improve noise immunity and thermal dissipation.
3 CE input Chip Enable (active-high on/off control). Drive high to enable the regulator, low to shut down. In shutdown (VCE=0V) the leakage current ISHD is ±1uA typical. Must not be left floating.
4 NC unconnected No internal connection. Leave floating or tie to GND for mechanical stability; do not use as a routing via.
5 VOUT power_out Regulated output voltage. The -T12 suffix fixes VOUT = 1.2V (accuracy ±1%). Rated for 300mA continuous, protected at 450mA (OCP) and clamped to 20mA on hard short (SCP). Requires at least 1uF ceramic output capacitor for stability.

Provenance

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

  • Datasheet: LR datasheet (11 pp, sha256 ea7990dc609a970a, 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.
