低压差稳压器 350mA Dual-Rail Linear Regulator 5-DSBGA -40 to 125
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.
