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 is offered in a 5-pin
TO-263 while SPX29302 is offered in a 5-pin
TO-263 and 5-pin TO-220 packages.

However, a minimum value of 10μF aluminum © 2010 Exar Corporation capacitor will guarantee stability over all load conditions. A tantalum capacitor is recommended if a faster load transient response is needed. If the power source has high AC impedance, a 0.1μ ...
