SPX

SPX Superpower Regulator, maximum performance and fixed or variable Vout

SPX with variable output is shipped with 30V out. Add a ¼W resistor between the two holes near the pins to change to any Vout down to 5V. Or you can order with a standard fixed output voltage as a plug-in LM78xx replacement!

  • Output variable with a single resistor, 5V to 30V
  • Positive or negative output available
  • 3A output current
  • World's lowest output impedance
  • Drop out <1V at 2A (positive output), <2V (negative output)
  • 120dB ripple rejection,
    DC to >50kHz
  • <1µV/Vout RMS noise, 20Hz-20kHz
  • 1µsec recovery time for 250mA current step
  • Fits TO-220 footprint and heat sink attachment
  • Insulated output transistor-- no thermal pad needed!
