LP2951  
100 mA Low-Dropout Voltage Regulator  
Features  
General Description  
• High Accuracy 5V, Guaranteed 100 mA Output  
• Extremely Low Quiescent Current  
• Low-Dropout Voltage  
The LP2951 is micropower voltage regulators with very  
low dropout voltage (typically 40 mV at light loads and  
380 mV at 100 mA), and very low quiescent current  
(75 μA typical). The quiescent current of the LP2951  
increases only slightly in dropout, thus prolonging  
battery life. This feature, among others, makes the  
LP2951 ideally suited for use in battery-powered  
systems.  
• Extremely Tight Load and Line Regulation  
• Very Low Temperature Coefficient  
• Use as Regulator or Reference  
• Needs Only 1 μF for Stability  
• Current and Thermal Limiting  
Available system functions, such as programmable  
output voltage and logic-controlled shutdown, are  
available as well.  
• Error Flag Warns of Output Dropout  
• Logic-Controlled Electronic Shutdown  
• Output Programmable from 1.24V to 29V  
Additional features available with the LP2951 also  
include an error flag output that warns of a low output  
voltage, which is often due to failing batteries on the  
input. This may also be used as a power-on reset. A  
logic-compatible shutdown input is also available which  
enables the regulator to be switched on and off. This  
part may also be pin-strapped for a 5V output, or  
programmed from 1.24V to 29V with the use of two  
external resistors.  
Applications  
• Automotive Electronics  
• Voltage Reference  
• Avionics  
The LP2951 is available as either a -02 or -03 version.  
The -02 and -03 versions are guaranteed for junction  
temperatures from -40°C to +125°C; the -02 version  
has a tighter output and reference voltage specification  
range over temperature.  
The LP2951 have a tight initial tolerance (0.5% typical),  
a very low output voltage temperature coefficient which  
allows use as a low-power voltage reference, and  
extremely good load and line regulation (0.05%  
typical). This greatly reduces the error in the overall  
circuit, and is the result of careful design techniques  
and process control.
