An input-output difference of 0.6V or less may be achieved using the 150 mA output current source of the LM2930 3-terminal positive regulator. When low input voltages are used effectively, such as when an automobile battery is used in cold cranking circumstances, 5V circuitry may be powered appropriately with supply voltages as low as 5.6V. Additionally included are common regulator functions like thermal overload protection and current limit. Since the LM2930 and all controlled circuitry were initially intended for automotive applications, they are guarded against reverse battery installations and two battery jumps. In the event of line transients, such a load dump at 40V, when the regulator's input voltage briefly above the designated maximum working voltage, the regulator will instantly cut off to safeguard internal circuits as well as the load.

When powering 10mA loads, the LM2931-N positive voltage regulator has a very low quiescent current of 1 mA or less. Because of its special qualities and the extremely low input-output difference (0.2V for output currents of 10mA) needed for appropriate regulation, the LM2931-N is the perfect regulator for standby power systems. Applications include systems requiring up to 100mA of output current, memory standby circuits, CMOS and other low power processor power supply. The LM2931-N and all controlled electronics are shielded from reverse battery installations and two battery jumps because they were originally intended for automotive applications. When there are line transients, such a load dump (60V), the regulator will immediately shut down to safeguard the load and internal circuits in the event that the input voltage exceeds the maximum operating voltage for a brief period of time.

The positive voltage regulators LM2940-N and LM2940C have the capacity to supply 1 A of output current across the whole temperature range, with a dropout voltage of normally 0.5 V and a maximum of 1 V. Additionally, a circuit for quiescent current reduction has been incorporated, which lowers the ground current when the difference between the input and output voltages is greater than roughly 3 V. With an output current of 1 A and an input-output difference of 5 V, the quiescent current is correspondingly only 30 mA. Only in dropout mode does the regulator allow for higher quiescent currents. The LM2940N and LM2940C, together with all the controlled circuitry, are made specifically for vehicle applications and are guarded against reverse battery installations and two battery jumps.
