LP2957/LP2957A 5V Low-Dropout Regulator for µP Applications  
Check for Samples: LP2957, LP2957A  
1
FEATURES  
DESCRIPTION  
The LP2957 is a 5V micropower voltage regulator  
with electronic shutdown, error flag, very low  
quiescent current (150 µA typical at 1 mA load), and  
very low dropout voltage (470 mV typical at 250 mA  
load current).  
2
5V Output within 1.4% Over Temperature (A  
Grade)  
Easily Programmed for Snap-On/Snap-Off  
Output  
Ensured 250 mA Output Current  
Extremely Low Quiescent Current  
Output can be wired for snap-on/snap-off operation to  
eliminate transition voltage states where µP operation  
may be unpredictable.  
Low Input-Output Voltage Required for  
Regulation  
Output crowbar (50 mA typical pull-down current) will  
bring down the output quickly when the regulator  
snaps off or when the shutdown function is activated.  
Reverse Battery Protection  
Extremely Tight Line and Load Regulation  
Very Low Temperature Coefficient  
Current and Thermal Limiting  
The part has tight line and load regulation (0.04%  
typical) and low output temperature coefficient (20  
ppm/°C typical).  
Error Flag Signals when Output is out of  
Regulation  
The accuracy of the 5V output is ensured at room  
temperature and over the full operating temperature  
range.  
APPLICATIONS  
The LP2957 is available in the five-lead TO-220 and  
DDPAK/TO-263 packages.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam  
during storage or handling to prevent electrostatic damage to the MOS gates.
