REF102AU from Texas Instruments TI, in a SOIC-8. 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 NC unconnected No internal connection. Leave floating or tie to a copper pad for mechanical support.
2 V+ power_in Positive supply input. Operating range +11.4VDC to +36VDC; absolute maximum input voltage +40V. Quiescent current 1.4mA max at IOUT = 0.
3 NC unconnected No internal connection. Leave floating.
4 Com power_in Common (ground) return for the reference. Establishes the 0V node from which the +10V VOUT is referenced.
5 Trim input Optional user trim input tapping the internal R5 (~50kOhm) divider. Allows small external adjustment of the output voltage with minimal effect on drift and stability; typical trim range approximately +/-3%. Leave floating if unused.
6 VOUT output +10V precision reference output. Initial accuracy +/-10mV (A), +/-5mV (B), +/-2.5mV (C). Sources up to +10mA and sinks up to -5mA; short-circuit protected to Com or V+.
7 NC unconnected No internal connection. Leave floating.
8 NR passive Noise Reduction pin. Ties to the top of the internal ~7kOhm resistor R6 across the zener. Connect an external capacitor from this pin to Com/ground to form a low-pass filter that rolls off high-frequency zener noise. Leave floating for normal (unfiltered) operation.

CAD (KiCad official)

  • Symbol: REF102AU
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: ref102au-etched.step / ref102au-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ref102au.step / ref102au.glb are the bare package body.

Provenance

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