SPX1585数据手册集成电路（IC）的线性+开关稳压器规格书PDF

描述 Description

The SPX1585 is a low power 5A, adjustable and fixed voltage regulator that is very easy to use. It requires only two external resistors to set the output voltage for the adjustable version. The SPX1585 devices are 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 microprocessors 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 SPX1585 features low dropout of a maximum 1.2 volts.
The SPX1585 offers full protection against overcurrent 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 SPX1585 devices are offered in a 3-pin TO-220 and TO-263 package compatible with other 3-terminal regulators. For an 8A low dropout regulator, refer to the SPX1584 datasheet.
