REF5050IDGKR

Texas Instruments · Voltage References · VSSOP-8-0.65mm

REF5050IDGKR from Texas Instruments, in a VSSOP-8-0.65mm. 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 - has no internal connection and should not be externally connected.
2 VIN power_in Supply voltage input accepting VOUT + 0.2V to 18V with maximum quiescent current of 1.2mA (-40°C to 125°C).
3 TEMP output Temperature sensor output providing 575mV nominal at 25°C with 2.64mV/°C sensitivity and high source impedance for monitoring die temperature.
4 GND power_in Reference ground providing return path for circuit currents up to ±10mA.
5 TRIM/NR passive Trim/noise reduction node with high output impedance for connection to external capacitors for filtering or resistor networks for ±15mV output adjustment.
6 VOUT power_out Precision 5.0V reference voltage output sourcing or sinking ±10mA with ±0.05% initial accuracy and 3ppm/°C temperature coefficient.
7 NC unconnected No internal connection - may be left floating or connected to ground without affecting circuit operation.
8 DNC unconnected Do Not Connect - has no internal connection and should not be externally connected.
