LM2931 datasheet



The LM2931 series consists of positive fixed and adjustable output  voltage regulators that are specifically designed to maintain proper  regulation with an extremely low input−to−output voltage differential.


1. Very low quiescent current
2. Output current in excess of 100 mA
3. Input-output differential less than 0.6V
4. Reverse battery protection
5. 60V load dump protection
6. −50V reverse transient protection
7. Short circuit protection
8. Internal thermal overload protection
9. Mirror-image insertion protection


Text :

The LM2931 positive voltage regulator features a very low quiescent current of 1mA or less when supplying 10mA loads. This unique characteristic and the extremely low input-output differential required for proper regulation (0.2V for output currents of 10mA) make the LM2931 the ideal regulator for standby power systems. Applications include memory standby circuits, CMOS and other low power processor power supplies as well as systems demanding as much as 100mA of output current.  [ … ]
