REF5050IDR

Texas Instruments · Voltage Reference · SOIC-8

REF5050IDR from Texas Instruments, in a SOIC-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; pin is not internally connected and is reserved for future functionality.
2 VIN power_in Supply voltage input accepting voltage from VOUT + 0.2V to 18V maximum at specified load conditions.
3 TEMP output Temperature monitoring output providing voltage proportional to die temperature at 2.64 mV/°C sensitivity over -40°C to 125°C range with approximately 60kΩ source impedance.
4 GND power_in Ground reference and return path for supply and output load currents.
5 TRIM/NR passive Trim and noise reduction pin allowing ±15mV adjustment of VOUT or passive RC filtering when capacitor is connected between pin and GND.
6 VOUT output Reference voltage output of 5.0V nominal with ±10mA output current capability and 1μF to 50μF load capacitance range.
7 NC unconnected No internal connection; pin is not used in this device variant.
8 DNC unconnected Do not connect; pin is not internally connected and is reserved for package compatibility.
