5A Low Dropout Voltage Regulator
Adjustable & Fixed Output, Fast Response Time
SPX29500/01/02/03
DESCRIPTION
FEATURES
■ Adjustable Output Down to 1.25V
■ 1% Output Accuracy
■ Output Current of 5A
■ Low Dropout Voltage: 370mV @ 5A
■ Tight Line Regulation: 0.06%
■ Load Regulation: 0.2%
■ Fast Transient Response
■ Reverse-Battery Protection
■ Current Limit and Thermal Protection
The SPX29500/01/02/03 are 5A highly accurate voltage regulators with a low dropout voltage of 370mV
@ 5A. 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. Other features in the 5 pin versions include Enable, and Error Flag.
The SPX29500/01/02/03 are offered in 3 & 5-pin TO-220 & TO-263 packages. For a 1.5A version, refer
to the SPX29150 data sheet. For a 3A version, refer to the SPX29300 datasheet.
