描述 Description

General Description
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 stand by circuits, CMOS and other low power processor power supplies as well as systems demanding as much as 100mA of output current.
