1 / 13 page Rev A 8/5/06 SP2950/5/52/53 .5A Low Dropout voltage Regulator © Copyright 2006 Sipex Corporation 1.5A Low Dropout Voltage Regulator SPX29150/51/52/53 DESCRIPTION FEATURES ■ Adjustable Output Down to 1.25V ■ 1% Output Accuracy ■ Output Current of 1.5A ■ Low Dropout Voltage of 390mV @ 1.5A ■ Extremely Tight Load and Line Regulation ■ Extremely Fast Transient Response ■ Reverse-Battery Protection ■ Zero Current Shutdown (5 pin version) ■ Error Flag Signal Output for Out of Regulation State (5 pin version) ■ Standard TO-220 and TO-263 Packages The SPX29150/51/52/53 are 1.5A, highly accurate voltage regulators with a low dropout voltage of 390mV (typical) @ 1.5A. These regulators are specifically designed for low volt- age 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 SPX29150/51/52/53 is offered in 3-pin and 5-pin TO-220 & TO-263 packages. For a 3A version, refer to the SPX29300 data sheet.
