SPX2954M3-L-3-3

MaxLinear · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-3

SPX2954M3-L-3-3 from MaxLinear, in a SOT-223-3. 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 Unregulated input supply; absolute maximum -0.3V to 30V, and a 1µF capacitor to ground is advised if the input has more than 10 inches of wire or is a battery.
2 GND power_in Ground reference for the regulator.
3 VOUT power_out Regulated 3.3V output for this variant, up to 250mA, needing at least 1µF to ground for stability.
