Overview
SPX29300 / SPX29301 / SPX29302 Data Sheet 3A Low Dropout Voltage Regulator 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.
Features ■ 3A guaranteed output current ■ Low dropout voltage of 600mV @ 3A ■ Adjustable output down to 1.
25V ■ 1% output accuracy ■ Tight load and line regulation ■ Fast transient response ■ Reverse battery protection ■ Zero current shutdown (SPX29301/02) ■ Power Good flag (SPX29301) ■ Lead free 3-pin TO-263 and 5-pin TO-263 packages Applications ■ Adjustable power supplies ■ Constant current regulators ■ Audio and video / graphic cards ■ Battery chargers Ordering Information - page 9 Typical Application Diagram Figure 1: SPX29300 and SPX29302 Application Diagrams • www.
