LP5952 350mA Dual Rail Linear Regulator
January 2007
LP5952
350mA Dual Rail Linear Regulator
General Description
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 V
BATT
is directly con-
nected to the battery (range 2.5V...5.5V) and V
IN
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 tem-
perature range.
The LP5952 is available in a micro SMD 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.

Note:
The actual physical placement of the package marking will vary from part to part. The package marking “X” designates the
date code. “T” is a NSC internal code for die traceability. Both will vary considerably. “U” identifies the device (part number, option,
etc.).
