DESCRIPTION  
The LM2751 is  
capacitor charge pump with regulated output voltage  
options of 4.5V, and 5.0V. Over the input voltage  
range of 2.8V to 5.5V the LM2751 provides up to  
150mA of output current and requires only four low-  
cost ceramic capacitors.  
Input Voltage Range: 2.8V to 5.5V  
Low Input and Output Voltage Ripple  
<1µA Typical Shutdown Current
