LM2772 - Texas Instruments

LM2772 Step-Down Regulator

The LM2772 is a switched capacitor step-down regulator that produces a 1.2V output. It is capable of supplying loads up to 150mA with 3% output voltage regulation over line, load, and temperature. The LM2772 operates with an input voltage from 3.0V to 5.5V, accommodating 1-cell Li-Ion batteries and chargers. The LM2772 utilizes a highly efficient regulated m.
