Legendsemi · Voltage Reference · SOT-23-3
LHR4020DFGR from Legendsemi, in a SOT-23-3. 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 | VIN | power_in | Supply voltage input; the recommended VIN is VOUT + 0.2 V to 5.5 V (VIN minimum is 2.5 V for every part except LHR4020), and the absolute maximum input voltage is -0.2 V to 7 V. |
| 2 | VOUT | output | Reference voltage output that sources and sinks up to ±10 mA, with a 0.1 µF to 10 µF output capacitor required from VOUT to GND and an absolute maximum output-to-ground short-circuit current of 30 mA. |
| 3 | GND | power_in | Ground reference pin for the device. |
