The LP5952 is a Dual Supply Rail Linear Regulator optimized for powering ultra-low
voltage circuits from a single Li-Ion cell or 3 cell NiMH/NiCd batteries.
In the typical post regulation application VBATT is directly
connected to the battery (range 2.5V...5.5V) and VIN is supplied by the
output voltage of the DC-DC Converter (range 0.7V...4.5V).
The device offers superior dropout and transient features combined with very low
quiescent currents. In shutdown mode (Enable pin pulled low) the device turns off and reduces
battery consumption to 0.1µA (typ.).
The LP5952 also features internal protection against over-temperature, over-current and
Performance is specified for a -40°C to 125°C junction temperature range.
The device is available in a tiny 5-bump DSBGA and a 6-pin Chip On Lead USON package,
The device is available in fixed output voltages in the range of 0.5V to 2.0V. For
availability, please contact your local Texas Instruments sales office.
