REF2033AIDDCR

Texas Instruments · Voltage Reference · SOT-23-5

REF2033AIDDCR from Texas Instruments, in a SOT-23-5. 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 VBIAS output Bias voltage output (VREF / 2). For the REF2033 this is 1.65 V nominal. Can source and sink up to ±20 mA.
2 GND power_in Ground return for the device.
3 EN input Enable input. Device is enabled when EN >= VIN - 0.7 V; device enters shutdown when EN <= 0.7 V. Absolute max range -0.3 V to VIN + 0.3 V.
4 VIN power_in Input supply voltage. Recommended range VREF + 0.02 V (typ) to 5.5 V; absolute max 6 V.
5 VREF output Reference voltage output. For the REF2033 this is 3.3 V nominal with 0.05% max initial accuracy. Can source and sink up to ±20 mA; stable with 0-10 µF output capacitor.
