Note 1: Output or reference voltage temperature coefficients  
defined as the worst case voltage change divided by the total  
temperature range.  
supply voltage of 2V (2.3V over temperature) must be taken  
into account.  
Note 6: Vref < Vout < (Vin-1V), 2.3V < Vin < 30V,  
100µA < IL < 100mA, TJ < TJMAX.  
Note 2: Unless otherwise specified all limits guaranteed for  
TJ=25oC, Vin=6V, IL=100µA and CL=100µF. Additional  
conditions for the 8-pin versions are feedback tied to 5V tap  
output Sense (Vout=5V) and Vshutdown<0.8V.  
Note 7: Output or reference voltage temperature coefficient  
is defined as the worst case voltage change divided by the  
total temperature range.  
Note 3: Regulation is measured at constant junction  
temperature, using pulse testing with a low duty cycle.  
Changes in output voltage due to heating effects are covered  
under the specification for thermal regulation.  
Note 8: Comparator thresholds are expressed in terms of a  
voltage differential at the feedbackterminal below the  
nominal reference voltage measured at 6V input . To  
express these thresholds in terms of output voltage change,  
Note 4: Line regulation for the LP2951 is tested at 150oC  
for IL=1mA. For IL=100µA and TJ=150oC, line regulation is  
guaranteed by design to 0.2%. See typical performance  
characteristics for line regulation versus temperature and  
load current.  
multiply  
by  
the  
error  
amplifier  
gain=Vout/Vref=(R1+R2)/R2. For example, at a programmed  
output voltage of 5V, the Error output is guaranteed to go  
low when the output drops by 95mV X 5V/1.235=384mV.  
Thresholds remain constant as a percent of Vout as Vout is  
varied with the dropout warning occuring at typically 5%  
below nominal, 7.5% guaranteed.  
Note 5: Dropout Voltage is defined as the input to output  
differential at which the output voltage drops 100mV below  
its nominal value measured at 1V differential at very low  
value of programmed output voltage, the minimum input  
Note 9: Vshutdown>2V, Vin < 30V, Vout = 0, Feedback pin tied to  
5V Tap.
