- Uninterrupted +3.3V Output
- Up to 500mA Output Current
- High-Power 0.9W SO-8 Package
- Thermal and Overcurrent Protection
- Only 1µF Output Capacitor
- Internal 0.18Ω +3.3V Auxiliary Switch
- No Reverse Current to Inactive Inputs
- Modem Cards
- Network-Interface Cards
- PCI Adapter Cards
An auxiliary switch resistance of only 0.18Ω minimizes output drop from the +3.3V auxiliary supply. In addition,the MAX1810 guarantees that no reverse current flows from the output to any unbiased or inactive input, and remains stable with as little as 1µF of output bypass capacitance at its output.
The MAX1810 is available in a compact 8-pin high-power(0.9W) SO package.
