25V Or Fixed 3.
3V • Output Current Of 4A • Low Dropout Voltage • Extremely Tight Load And Line Regulation • Current & Thermal Limiting • Standard 3-Terminal Low Cost TO-220 APPLICATIONS • Powering Intel Pentium µP from +5V Supplies • Power PC Supplies • SMPS Post-Regulator • High Efficiency “Green” Computer Systems • High Efficiency Linear Power Supplies • Portable Instrumentation • Constant Current Regulators • Adjustable Power Supplies • Battery Charger PRODUCT DESCRIPTION The SPX2840 is a low power 4A Adjustable Voltage Regulator that is very easy to use.
It requires only 2 external resistors to set the output voltage.
This device is an excellent choice for use in Powering Intel Microprocessor to convert from +5V to 3.
3V supplies and as a post regulator for switching supplies applications.
The SPX2840 features low dropout of a maximum 1.
3 volts.
The SPX2840 offers over-current limit and full protection against reversed input polarity, reversed load insertion, over temperature operation, and positive and negative transient voltage.
On-Chip trimming adjusts the reference voltage to 1%.
The IQ of this device flows in to the load, which increases the efficiency.
The SPX2840 is offered in a 3-pin TO-220 package compatible with other 3 terminal regulators.
For a 3A low dropout regulator refer to the SPX2830 data sheet.
