|
December 2016
GENERAL DESCRIPTION
The SPX29300/01/02 are 3A, highly accurate
voltage regulators with a low dropout voltage of
600mV (typical) at 3A.
These regulators are specifically designed for
low voltage applications that require a low
dropout voltage and a fast transient response.
They are fully fault protected against over-
current, reverse battery, and positive and
negative voltage transients. On-Chip trimming
adjusts the reference voltage to 1% initial
accuracy.
The SPX29300 is offered in a 3-pin TO-263
package, the SPX29301 and SPX29302 are
offered in a 5-pin TO-263 package.
