LTC3260  
Low Noise Dual Supply  
Inverting Charge Pump  
FeaTures  
DescripTion  
The LTC®3260 is a low noise dual polarity output power  
supply that includes an inverting charge pump with both  
positive and negative LDO regulators. The charge pump  
operatesoverawide4.5Vto32Vinputrangeandcandeliver  
up to 100mA of output current. Each LDO regulator can  
provide up to 50mA of output current. The negative LDO  
post regulator is powered from the charge pump output.  
The LDO output voltages can be adjusted using external  
resistor dividers.
