Product Summary
The SPX1582T5/TR is a 3A 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. The SPX1582T5/TR features a low dropout of 400mV(Typ.) and offers fast transient response. With an external sense pin the load regulation is less than 1mV. This device is an excellent choice for the use of powering low voltage microprocessors that require a lower dropout, fast transient response to regulate from 3.3V and 5V supplies. The SPX1582T5/TR is also an excellent choice as a post regulator for switching supplies applications. The SPX1582T5/TR offers protection against over-current faults, reversed input polarity, over temperature operation and positive and negative transient voltage. Applications are (1)3.3V to 2.8V ATX Power Supplies; (2)3.3V to 2.9V for Portable PENTIUMTM Processor; (3)5V to 3.5V VRE Supply; (4)High efficiency "Green" Computer Systems.
