SPX2954M3-3.3

MaxLinear · Linear Voltage Regulators (LDO) · SOT-223-4

SPX2954M3-3.3 from MaxLinear, in a SOT-223-4. 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 Unregulated input supply, rated -0.3V to +30V absolute maximum.
2 GND power_in Ground reference for the regulator, internally connected to the tab.
3 VOUT power_out Regulated 3.3V output rated for 250mA, which needs at least 1µF to ground for stability.
4 TAB power_in Package tab, internally connected to GND on the SOT-223.
