REF35300QDBVR

Texas Instruments · Voltage Reference · SOT-23-6

REF35300QDBVR from Texas Instruments, in a SOT-23-6. 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 GND power_in Device ground connection; on the DBV package pin 1 and pin 2 are internally shorted.
2 GND power_in Device ground connection, internally shorted to pin 1 on the DBV package.
3 EN input Enable connection that enables or disables the device.
4 VIN power_in Power input supply voltage connection.
5 NR output Noise reduction pin; connect a capacitor to reduce noise, and this pin can be left floating.
6 VREF power_in Reference voltage output.
