VDA1120CTA

AnaSem · Voltage References · SOT-23

VDA1120CTA from AnaSem, in a SOT-23. 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 VOUT output Output terminal; the output voltage follows VIN when VIN is above the release voltage and is pulled to VSS when VIN is below the detection voltage, with an output current rating of 50 mA and an output voltage range of VSS -0.3 V to VIN +0.3 V.
2 VSS power_in Power ground reference for the device, with the output voltage range referenced to VSS (VSS -0.3 V minimum).
3 VIN power_in Voltage input and supply for the detector, with an operating voltage range of 0.7 V to 6.0 V and an absolute maximum input voltage range of -0.3 V to +7.0 V.
