Legendsemi(领慧立芯) · Voltage Reference · MSOP-8
LHR3025BFMA from Legendsemi(领慧立芯), in a MSOP-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 | DNC | unconnected | Do not connect; leave this pin unconnected. |
| 2 | VIN | power_in | Supply voltage input; the recommended VIN range is VOUT + 0.2V to 18V, the absolute maximum input voltage is 18V, and the minimum supply is 2.7V for LHR3025 (VOUT ≤ 2.5V). |
| 3 | TEMP | output | Temperature monitor output providing a temperature-dependent voltage (about 640 mV + 2.08 mV/°C × T, ±15 °C accuracy), with high output impedance so low-impedance loads should be avoided or buffered. |
| 4 | GND | power_in | Ground reference pin; the output capacitor CL (1 µF to 50 µF) must be connected from VOUT to GND. |
| 5 | NC | unconnected | No internal connection; this pin can be left unconnected. |
| 6 | VOUT | output | Voltage reference output that sources and sinks up to ±10 mA load current, requires a 1 µF to 50 µF output capacitor to GND, and has an absolute short-circuit limit of 70 mA to ground per the absolute maximum ratings. |
| 7 | DNC | unconnected | Do not connect; leave this pin unconnected. |
| 8 | DNC | unconnected | Do not connect; leave this pin unconnected. |
