产品概述
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 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.Depending upon application, only one or two tiny surface-mount external components are
required; performance is specified for a –40°C to +125°C junction temperature range. The device is
available in fixed output voltages from 0.5 V to 2 V. For availability, please contact your local
Texas Instruments sales office.
