LN1154B282MR-G

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

LN1154B282MR-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 Positive supply input. Operating range 2.0 V to 7 V (absolute max VSS-0.3 V to VSS+8 V). A 2.2 µF or larger input capacitor (C1) between VIN and VSS is required for stability.
2 VSS power_in Ground / device negative reference. All voltages are referenced to VSS.
3 CE input Chip Enable. Active-high (B option): drive ≥1.6 V (VCEH) to enable the regulator, ≤0.5 V (VCEL) to shut it down. The 'B' suffix version has an internal pull-down resistor, so leaving CE floating disables the part. Absolute max VSS-0.3 V to VIN+0.3 V.
4 NC unconnected No connection. Leave floating or tie to any potential; not internally bonded on the SOT-23-5 variant.
5 VOUT power_out Regulated output. Fixed 3.95 V (VOUT(S)×0.98 to ×1.02 for the ±2% grade indicated by the '...2' accuracy code). Delivers up to 300 mA with VIN ≥ VOUT+1 V. A 2.2 µF or larger output capacitor (C2) is required for stability. An internal bleed/discharge transistor pulls VOUT down when the part is disabled.

Provenance

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

  • Datasheet: NATLINEAR datasheet (None pp, sha256 144e00042d3b9baf, 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).
