REF102CU

Texas Instruments · Voltage Reference · SOIC-8

REF102CU from Texas Instruments, in a SOIC-8. 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 NC unconnected Not connected; the datasheet marks this pin as NC with no internal connection.
2 V+ power_in Positive supply input; single-supply operation from 11.4V to 36V is specified.
3 NC unconnected Not connected; the datasheet marks this pin as NC with no internal connection.
4 Com power_in Common (ground) reference for the reference; interconnection resistance should be minimized.
5 Trim input Output voltage trim input; trim range is ±3% and trimming slightly affects drift.
6 VOUT power_out 10V precision reference output; output current is specified at +10mA source and -5mA sink.
7 NC unconnected Not connected; the datasheet marks this pin as NC with no internal connection.
8 Noise Reduction passive A capacitor from this pin to ground forms a low-pass filter with internal R6 to attenuate zener noise.

CAD (KiCad official)

  • Symbol: REF102CU
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: ref102cu-etched.step / ref102cu-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ref102cu.step / ref102cu.glb are the bare package body.

Provenance

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