CP2128 is a low-noise, frequency-fixed booster DC/DC converter, under the condition that the voltage is 2.7~4.5V, the device is outputting a voltage os 5V, its max output current can reach 100mA. Cp2128 needs very few external elements, so it is suitable for micro and batter-powered conditions. CP2128 can reduce the output and input drift from zero to full load. CP2128 has the over-heat protection function, which can afford the continuous UOUT ground connection.
