Desktop PC's Servers Powering VGA and Sound Cards Cordless Phones Battery Chargers Adjustable Power Supplies Portable Instrumentation SMPS Post-Regulator

The 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 computers. The SPX1587 features very low quiescent current and a low dropout voltage at a full load. As output current decreases, quiescent current flows into the load, increasing efficiency. SPX1587 is available in adjustable or fixed 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.

NOTES: Note 1: Output temperature coefficient is defined as the worst case voltage change divided by the total temperature range Note 2: Dropout voltage is defined as the input to output differential at which the output voltage drops 100mV below its nominal value measured at 1V differential at very low values of programmed output voltage, the minimum input supply voltage ( 2.3V over temperature) must be taken into account. Note 3: Thermal regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied. excluding load or line regulation effect. Note 4: Adjustable Version Only.
