DescriptionThe 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 under-voltage conditions.
Performance is specified for a -40°C to 125°C junction temperature range.
The device is available in a tiny 5-bump micro SMD and a 6-pin Chip On Lead LLP package, lead free.
The device is available in fixed output voltages in the range of 0.5V to 2.0V. For availability, please contact your local NSC sales office.
