Maxim's MAX1810 is a smart regulator for Ethernet network interface cards (NICs), modem cards and other devices that are system compliant with PCI. The MAX1810 delivers an uninterrupted +3,3 V at up to 500 mA from a +5 V main supply, or a 3,3 V auxiliary supply. When both main and standby supplies drop below 4,1 V, an internal switch connects the PCI system's +3,3 V auxiliary input to the output. The internal switch is only 0,18 W and minimises voltage drop from the auxiliary supply.
The main and standby inputs generate the +3,3 V output via CMOS linear regulators with excellent line and load regulation. Only a 1 µF ceramic capacitor is required at the output to guarantee stability. Under short-circuit conditions, the output current is limited to 900 mA. Thermal-overload protection turns off the MAX1810 if the chip temperature exceeds +170°C. Special circuitry also prevents reverse current from flowing from the output to any inactive or low-voltage input.
The MAX1810 is available in a compact, high-power 8-pin SO package, capable of dissipating up to 0,9 W.
