LHR3020BFAA

Legendsemi · Voltage Reference · SOP-8

LHR3020BFAA from Legendsemi, in a SOP-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 DNC unconnected Do Not Connect. Reserved/internal test pin; must be left electrically floating on the PCB. Do not tie to GND, VIN, or any signal.
2 VIN power_in Positive supply input. Operating range VOUT+0.2V to 18V (LHR3020: VIN min = VOUT+0.2V; other variants ≥2.7V). Absolute maximum -0.2V to 18V. Bypass with 1 µF to 10 µF placed close to the pin.
3 TEMP output Temperature-monitor analog output. High-impedance node following VTEMP = 668 mV + 1.91 mV/°C × T; accuracy ≈ ±15°C. Buffer with a low-drift op-amp when driving low-impedance loads to avoid measurement error; loading this pin does not affect VOUT accuracy.
4 GND power_in Device ground / 0 V reference return for VIN, VOUT, and TEMP.
5 NC unconnected No Internal Connection. Pin is not bonded internally; may be left floating or tied to a plane at the designer's discretion.
6 VOUT power_out Precision reference voltage output. Nominal 2.048 V for LHR3020, initial accuracy ±0.1% (B-grade), drift 8 ppm/°C max. Sinks/sources up to ±10 mA. Must be decoupled to GND with a 1 µF to 50 µF output capacitor.
7 DNC unconnected Do Not Connect. Reserved/internal test pin; must be left electrically floating on the PCB.
8 DNC unconnected Do Not Connect. Reserved/internal test pin; must be left electrically floating on the PCB.
