DESCRIPTION  
The LM2750 is  
a regulated switched-capacitor  
•
Output Current up to 120mA with 2.9V ≤ VIN ≤  
5.6V  
doubler that produces a low-noise output voltage. The  
5.0V output voltage option (LM2750-5.0) can supply  
up to 120mA of output current over a 2.9V to 5.6V  
input range, as well as up to 40mA of output current  
when the input voltage is as low as 2.7V. An  
adjustable output voltage option with similar output  
current capabilities is also available (LM2750-ADJ).  
The LM2750 has been placed in TI's 10-pin WSON, a  
package with excellent thermal properties that keeps  
the part from overheating under almost all rated  
operating conditions.

Wide Input Voltage Range: 2.7V to 5.6V  
Fixed 1.7MHz Switching Frequency for a Low-
