SPX1585AT-1.5 General Description

The SPX1585AT-1.5 is one member of the SPX1585 series.The SPX1585AT-1.5 are low power 5A adjustable and fixed voltage regulators that are very easy to use.It requires only 2 external resistors to set the output voltage for adjustable version.The SPX1585AT-1.5are designed for low voltage applications that offer lower dropout voltage and faster transient response. This device is an excellent choice for use in powering low voltage microprocessor that require a lower dropout, faster transient response to regulate from +2.5V to 3.8V supplies and as a post regulator for switching supplies applications. The SPX1585AT-1.5 features low dropout of a maximum 1.2 volts.

Features of the SPX1585AT-1.5 are:(1)adjustable output down to 1.2V;(2)fixed output voltages 1.5V, 2.5V, 3.3V;(3)output current of 5A;(4)low dropout voltage 1.1V typ @ 5A.;(5)extremely tight load and line regulation;(6)current & thermal limiting;(7)standard 3-terminal low cost to-220 & to-263;(8)similar to industry standard LT1085/LT1585.The SPX1585AT-1.5 offers full protection against over-current faults, reversed input polarity, reversed load insertion, and positive and negative transient voltage. On-Chip trimming adjusts the reference voltage to 1%.The IQ of this device flows into the load, which increases efficiency.

The absolute maximum ratings of the SPX1585AT-1.5 can be summarized as:(1)lead temp. (soldering, 10 seconds):300°C;(2)storage temperature range :-65 to +150°C;(3)input voltage:10V ;(4)input to output voltage differential:10V.The SPX1585 incorporates protection against over-current faults, reversed load insertion, over temperature operation, and positive and negative transient voltage. However, the use of an output capacitor is required in order to insure the stability and the performances. Although the SPX1585 offers some limiting circuitry for overload conditions, it is necessary not to exceed the maximum junction temperature, and therefore to be careful about thermal resistance. The heat flow will follow the lowest resistance path, which is the Junction-to-case thermal resistance. In order to insure the best thermal flow of the component, a proper mounting is required. Note that the case of the device is electrically connected to the output. In case the case has to be electrically isolated, a thermally conductive spacer can be used. However do not forget to consider its contribution to thermal resistance.
