LP5952 Overview
The LP5952 is a dual-supply-rail linear regulator optimized for powering ultralow-voltage circuits from a single Li-Ion cell or 3-cell NiMH/NiCd battery. In the typical post-regulation application VBATT is directly connected to the battery (range 2.5 V to 5.5 V), and VIN is supplied by the output voltage of the DC-DC converter (range 0.7 V to 4.5 V). The device offers superior dropout and transient.
