LM2750 Low Noise/ 5.0V Regulated Switched Capacitor Voltage Converter

The LM2750 is a switched-capacitor doubler that produces a low-noise, well regulated, 5.0V output. It 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. The LM2750 has been placed in National’s 1.
