SPX1587 Datasheet | MaxLinear

DESCRIPTION The SPX1587 is a low power positive-voltage regulator designed to satisfy moderate power requirements with a cost effective, small footprint solution. This device is an excellent choice for use in battery-powered applications and portable puters. The SPX1587 features very low quiescent current and a low dropout voltage of 1.1V at a full load. As output current decreases, quiescent current flows into the load, increasing efficiency. SPX1587 is available in adjustable or fixed 1.5V, 2.5V, 3.3V and 5.0V output voltages. The SPX1587 is offered in several 3-pin surface mount packages: TO-252, TO-220 and TO-263. An output capacitor of 10μF ceramic or tantalum provides unconditional stability. Adjustable and 3.3V TO-263 available, TO-252 and TO-220 obsolete versions versions FUNCTIONAL DIAGRAM 3A Low Dropout Voltage Regulator Rev. 2.0.1 APPLICATIONS - Desktop PC's Servers - Powering VGA and Sound Cards - Adjustable Power Supplies - Portable Instrumentation FEATURES - Guaranteed 3A Output Current - Three Terminal Adjustable or Fixed 1.5V, 2.5V, 3.3V and 5.0V - Low Quiescent Current - Low Dropout Voltage: 1.1V at 3A - Line Regulation: 0.1% - Load Regulation: 0.1% - Stable with 10u F Ceramic Capacitor - Over Current and Thermal Protection - Similar to Industry Standard LT1587 - Ro HS pliant Lead Free 3-Pin TO-220, TO-252 and TO-263 Packages Fig. 1: SPX1587 Functional Diagram (Adjustable version) 1 ABSOLUTE MAXIMUM RATINGS These are stress ratings only and functional operation of the device at these ratings or any other above those indicated in the operation sections of the specifications below is not implied.
