ZGR1033AG1

Zynalog · Voltage Reference · SOT-23-3

ZGR1033AG1 from Zynalog, in a SOT-23-3. 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 VIN power_in Input supply voltage: recommended range is Vout + Vdrop to 5.5 V (absolute maximum 6 V, from -0.3 V), and if Vout is below 2.5 V the input must be at least 2.5 V.
2 VOUT power_out Voltage reference output, rated for load currents of -10 mA to +10 mA with output voltage absolute maximum of 5.5 V and short-circuit current of 22 mA (maximum, absolute rating).
3 GND power_in Ground reference pin for the device.
