LM2770 Datasheet (National Semiconductor) - High Efficiency Switched Capacitor Step-Down DC/DC Regulator

LM2770, High Efficiency Switched Capacitor Step-Down DC/DC Regulator

The LM2770 is a switched capacitor step-down regulator that is ideal for powering low-voltage applications in portable systems.

The LM2770 can supply load currents up to 250mA and operates over an input voltage range of 2.7V to 5.5V.

This makes the LM2770 a great choice for systems powered by 1-cell
