REF5050ID

Texas Instruments · Voltage References · SOIC-8

REF5050ID from Texas Instruments, in a SOIC-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; this pin is listed as 'Do not connect' in Table 5-1 for the REF50xxI.
2 VIN power_in Input supply voltage; the absolute maximum for REF50xxI is 18V and the recommended input is VOUT + 0.2V minimum to 18V.
3 TEMP output Temperature monitoring output giving VTEMP = 509mV + 2.64 × T(°C) for REF50xxI with about 60kΩ source impedance and ±15°C accuracy, and low-impedance loads cause measurement error.
4 GND power_in Ground reference pin for the device.
5 TRIM/NR passive Output adjustment or noise reduction pin on the REF50xxI; the datasheet gives no numeric limit for this pin on this grade.
6 VOUT output Reference voltage output (5.0V for REF5050), rated for ±10mA output current with an absolute maximum of 5.5V.
7 NC unconnected No internal connection on the REF50xxI.
8 DNC unconnected Do not connect.
