Meet SPX, the champion in voltage regulation

This year (2020) begins our second decade supplying the highest performance voltage regulators. We're glad to be able to deliver our products for so long and will continue to supply your future product needs as they change.

SPX—the new standard

Variable!	Set Vout with a single resistor, on all pinouts
Insulated Power Transistor	Attach directly to heat sink—no thermal pad!
Lowest output impedance	<25mΩ at 20kHz, 50mΩ at 200kHz
Highest ripple rejection	120dBV+ from DC to 80kHz
Fastest dynamic step response	1μsec settling for 250mA step
Very low noise	<1μV/V, as good as ever

Belleson has the broadest array of voltage regulators in the industry. You can have a super high performance regulator for your system, whatever voltage or current it requires!

• SPX 3.3V to 30V @ 3A V_out variable 5V to 30V!
• SPHP 3.3V to 100V @ 10A 1000 Watts!
• SPLV 1.2V to 2.5V @ 2A
• SPM 3.3 to 30V @ 220mA

The king is dead,
long live the King!
