SPX1581 - 5A Ultra Low Dropout Voltage Regulator

Datasheet Summary

Description

The SPX1581 is a 5A Low Dropout Regulator with extremely low dropout voltage.

The adjustable version requires only two external resistors to set the output voltage.

The fixed version has a preset output of 3.3V, 2.8V or 2.5V and does not require any external resistors.

Features

  • Low Dropout Voltage 500mV at 5A Full Load Current.
  • Adjustable Ouput Down to 1.2V from ATX Power Supply.
  • Fixed Output Voltages of 3.3V, 2.8V and 2.5V.
  • Extremely Tight Load and Line Regulation.
  • Standard 5-Terminal Low Cost TO-220 and TO-263 ADJ OR FIXED SENSE VCNTRL VOUT VIN SPX1581 5 Pin TO-263 SPX1581 5 Pin TO-220 1 2 3 4 5 1 2 3 4 5.
