XDS · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23
TX7533-T from XDS, 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 | VSS | power_in | Ground reference pin; all datasheet voltages are specified relative to VSS, and the pin is labeled VSS in the SOT23-3 top-view pinout (page 2). |
| 2 | VOUT | output | Fixed regulated output, 3.3V for the 7533-T with ±2% accuracy at VIN=VOUT+2V and IOUT=10mA, with output current up to 160mA as an absolute maximum rating. |
| 3 | VIN | power_in | Unregulated input supply, rated 55V maximum as an absolute maximum (40V in the electrical test conditions), and requires a decoupling capacitor of at least 1µF ceramic. |
