LN1154B332MR-G

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

LN1154B332MR-G from NATLINEAR, 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 Regulator supply input. Operating range 2.0 V to 7 V (absolute max VSS-0.3 V to VSS+8 V). Bypass to VSS with a 2.2 µF or larger ceramic capacitor.
2 VSS power_in Ground / common reference for the regulator.
3 CE input Chip-enable input. Active-high on the 'B' option (internal pull-down resistor). Logic high (VCEH ≥ 1.6 V) turns the regulator on; logic low (VCEL ≤ 0.5 V) shuts it down.
4 NC unconnected No internal connection. Leave floating or tie to VSS.
5 VOUT power_out Regulated 3.3 V output (±2% for the '2' accuracy grade). Delivers up to 300 mA when VIN ≥ VOUT + 1 V. Requires a 2.2 µF or larger output capacitor for stability; internal bleed transistor discharges the output when disabled.

Provenance

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

  • Datasheet: NATLINEAR datasheet (7 pp, sha256 0fe3f1530887c91c, 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).
