LP5952  
350mA Dual Rail Linear Regulator  
General Description  
Features  
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.  
Excellent load transient response: ±15mV typical  
Excellent line transient response: ±1mV typical  
0.7V VIN 4.5V  
In the typical post regulation application VBATT is directly con-  
nected 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).  
2.5V VBATT 5.5V  
0.5V VOUT 2.0V  
For ILOAD = 350mA:  
VBATT VOUT(NOM) + 1.5V or 2.5V whichever is higher  
For ILOAD = 150mA:  
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.).  
VBATT VOUT(NOM) + 1.3V or 2.5V whichever is higher  
50µA typical quiescent current from VBATT  
10µA typical quiescent current from VIN  
0.1µA typical quiescent current in shutdown  
Guaranteed 350mA output current  
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.  
Noise voltage = 100µVRMS typical  
The LP5952 is available in a micro SMD package, lead free.  
Operates from a single Li-Ion cell or 3 cell NiMH/NiCd  
batteries  
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.  
Only one or two tiny surface-mount external components  
required depending on application  
Small 5 bump micro SMD package, lead free  
Thermal-overload and short-circuit protection  
-40°C to +125°C junction temperature range  
Applications  
Mobile Phones  
Hand-Held Radios  
Personal Digital Assistants  
Palm-Top PCs  
Portable Instruments  
Battery Powered Devices
