com LM2771 Low-Ripple 2 50mA Switched Capacitor Step-Down DC/DC Converter March 2006 LM2771 Low-Ripp le 250mA Switched Capacitor Step-Down D C/DC Converter General Description The LM2771 is a switched capacitor step-dow n regulator that produces a 1.
5V output without the use of an inductor.
It is capable of supplying loads up to 250mA.
The LM2771 operates with an input volt age from 2.
7V to 5.
5V, and requires onl y 3 low-cost ceramic capacitors.
The LM 2771 uses a regulated 0.
5x charge pump to give power conversion efficiencies n early twice as high as an LDO.
Pre-regu lated 1.
