3.3V/5V掌上电脑及LCD电源稳压器

The MAX722 and MAX723 CMOS power-supply ICs create dual regulated DC outputs for small, battery-operated microprocessor systems. Each device generates a main output (3V or 5V, selectable) and a negative auxiliary output that is adjustable for LCDs. Each device accepts two input voltages. Power can c \n• Low 0.9V to 5.5V Battery Input Range \n• Unregulated 7V to 20V DC Input Range \n• Dual Regulated Outputs\n• Main Output: 3.3V/5V \n• Auxiliary Output: 0V to -100V\n• 87% Efficiency at 200mA \n• Efficient PRAM Keep-Alive: 80% at 1mA \n• 8W/in³ Power Density \n• 60µA Quiescent Current \n• ;
