LM2931 : 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. Designed originally for automotive applications, the LM2931 and all regulated circuitry are protected from reverse battery installations or 2 battery jumps. During line transients, such as a load dump (60V) when the i.

LM2931 : DATA SHEET www.onsemi.com LDO Voltage Regulator Adjustable Output, Load Dump Protection 60 V, 100 mA LM2931, NCV2931 Series 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. These devices are capable of supplying output currents in excess of 100 mA and feature a low bias current of 0.4 mA at 10 mA output. Designed primarily to survive in the harsh automotive environment, these devices will protect all external load circuitry from input fault conditions caused by reverse battery connection, two battery jump starts, and excessive line tra.

LM2931 : The LM2931 is a low power voltage regulator. This device excellent choice for use in battery powered. Furthermore, the quiescent current increases only slightly at dropout, which prolongs battery life. The LM2931 features very low quiescent current (100㎂ Typ.) and very low drop output voltage (Typ. 60㎷ at light load and 300㎷ at 100㎃). This includes a tight initial tolerance of 0.5% Typ., extremely good load and line regulation of 0.05% Typ., and very low output temperature coefficient. The LM2931 fixed-voltage and andjustable regulators is offered in 3-pin TO-92 package compatible with other fixed regulator.

LM2931 : The LM2931 are very low drop regulators. The very low drop voltage and the low quiescent current make them particular suitable for low noise, low power applications and in battery-powered systems. In the 8-pin configuration (SO-8), fully compatible with the older L78L family, a shutdown logic control function is available. This means that when the device is used as a local regulator it is possible to put a part of the board in standby, decreasing total power consumption. Ideal for automotive applications, LM2931 is protected from reverse battery installations or 2 battery jumps. During the transient, such as a 60 V load dump, when the input voltage can exceed the specified maximum operating .
