100mA Low Dropout Voltage Regulator  
LM2931  
Description  
Features  
Guaranteed 100mA Output  
The Bay Linear LM2931 are low power voltage regulators  
designed for a wide range of applications. They are an  
excellent choice for use in Battery Powered applications. The  
LM2931 feature low quiescent current (100 µA Typ.) and low  
dropout of only 60mV at light loads and 300mV (typ.) at  
100mA. The LM2931 has tight initial tolerance of 0.5% typ.,  
extremely good load and line regulation of 0.05% typ. and very  
low output temperature coefficient.  
Fixed Versions 3.3V, 50.V, 8.0  
Very Low Quiescent Current  
Low Dropout Voltage  
Extremely Tight Load and Line  
Regulation  
Very Low Temperature Coefficient  
Current and Thermal Limiting  
Reverse Battery Protection of –20V  
Transient protection of 60V  
The Bay Linear LM2931 is available as a fixed voltage  
regulator and as an adjustable regulator in TO-92 and 8SOIC  
packages. The Bay Linear LM2931 in an 8SOIC package has  
an adjustable output voltage from 3V to 24V, programmed  
with a pair of external resistor. The logic compatible shutdown  
enables the regulator to be switched ON and OFF.  
Output programmable from 3V to 24V
