Description

General part information

LP5952 Series

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 VBATTis directly connected to the battery (range 2.5 V to5.5 V), and VINis 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 features combined with very low quiescent currents. In shutdown mode (Enable (EN) pin pulled low) the device turns off and reduces battery consumption to 0.1 µA (typical). The LP5952 also features internal protection against overtemperature, overcurrent, and undervoltage conditions.
