LM45CIM3X

Texas Instruments · Temperature Sensors · SOT-23

LM45CIM3X from Texas Instruments, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 +VS power_in Positive supply voltage input, operating range +4.0V to +10V, drawing less than 120 µA quiescent current.
2 VO output Analog output voltage, linearly proportional to temperature at +10.0 mV/°C, with low output impedance of 20Ω for a 1 mA load.
3 GND power_in Ground pin, thermally attached to the backside of the die for good thermal conductivity to the sensed surface.

CAD (KiCad official)

  • Symbol: LM45CIM3X
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: lm45cim3x-etched.step / lm45cim3x-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm45cim3x.step / lm45cim3x.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (20 pp, sha256 8e8a97187b53b7db, retrieved 2026-09-24, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.2, primary claude-sonnet-5 (text+vision), consensus claude-opus-4-8 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
