LM4128DQ1MF2.0

Texas Instruments · Voltage Reference · SOT-23-5

LM4128DQ1MF2.0 from Texas Instruments, in a SOT-23-5. 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 N/C unconnected No connect pin; leave floating.
2 GND power_in Ground reference for the device.
3 EN input Enable pin: the datasheet specifies a maximum low input level (VIL) of 35 %V and a minimum high input level (VIH) of 65 %V, and enables the 3 µA shutdown mode when EN = 0 V.
4 VIN power_in Input supply; the maximum input supply voltage is 5.5 V.
5 VREF power_out Reference voltage output, rated for a maximum load current of 20 mA.

CAD (KiCad official)

  • Symbol: LM4128DQ1MF2.0
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: lm4128dq1mf2-0-etched.step / lm4128dq1mf2-0-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm4128dq1mf2-0.step / lm4128dq1mf2-0.glb are the bare package body.
