Overview
SPX1585 Data Sheet 5A Low Dropout Fast Response Voltage Regulator General Description The SPX1585 is a very easy-to-use low-power 5A adjustable and fixed voltage regulator.
It requires only two external resistors to set the output voltage for the adjustable version.
The SPX1585 device is 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 lower dropout and 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 of 1.
2V.
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 device is offered in a 3-pin TO-263 package compatible with other 3-terminal regulators.
