REF02BU

Texas Instruments · Voltage Reference · SOIC-8

REF02BU 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 NC unconnected No internal connection; leave floating.
2 VIN power_in Supply input, specified for 8V to 40V with absolute maximum input voltage of +40V.
3 Temp output Temperature voltage output, typically 630mV with a 2.1mV/°C temperature coefficient; it is insensitive to capacitive loading but shifts 7mV per µA of load current.
4 GND power_in Ground reference for the supply, output and trim network.
5 Trim input Output adjustment input; a 10kΩ potentiometer from VOUT to ground with its wiper here gives an output adjustment range of ±6%, with minimal effect on temperature coefficient.
6 VOUT power_out Precision 5V reference output, 4.990V to 5.010V for REF02B at 0mA load, short-circuit protected.
7 NC unconnected No internal connection; leave floating.
8 NC unconnected No internal connection; leave floating.
