TX7530-T

XDS · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3L

TX7530-T from XDS, in a SOT-23-3L. 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 for the regulator; all datasheet voltages are stated relative to VSS.
2 VOUT power_out Fixed 3.0 V regulated output (±2% accuracy) rated for 100 mA output current, requiring at least a 1 µF ceramic output capacitor.
3 VIN power_in Input supply with a 40 V electrical-characteristic rating (55 V absolute maximum), requiring a bypass capacitor of at least 1 µF ceramic.
