5 / 6 page 5 2003 Semtech Corp. www.semtech.com POWER MANAGEMENT EZ1580/EZ1581 EZ1582/EZ1583 The EZ158X is a low dropout regulator designed to power low voltage microcontrollers, graphics ICs, sound cards etc. The dropout voltage is minimized by utilizing a separate input voltage, V CTL, which should exceed VOUT by at least 1.3V. The 2.5V (for example) power for the load can be derived from a 3.3V system supply. Since the efficiency of a linear regulator is the ratio of the output to the input voltage, heat dissipation is reduced by using a 3.3V input (versus a 5V one), thereby lowering heatsink and cooling Applications Information fan costs. For lower current applications, the heatsink might be eliminated altogether. For a load of 7A at 2.5V, the regulator would dissipate 17.5W when converting from 5V, but only 5.6W from a 3.3V input. Remote Kelvin sensing of the output voltage can be achieved by connecting the sense pin to the output at the load. Remote sensing will reduce errors associated with resistive trace losses between regulator and processor. Outline Drawing - TO-263-5 Outline Drawing - TO-220-5 |
