ADP2140 General Description

The ADP2140 includes a high efficiency, low quiescent 600 mA stepdown dc-to-dc converter and a 300 mA LDO packaged in a small 10-lead 3 mm × 3 mm LFCSP. The total solution requires only four tiny external components. The buck regulator uses a proprietary high speed currentmode, constant frequency, p.
