LM2931-N www.ti.com SNOSBE5G – MARCH 2000 – REVISED APRIL 2013 LM2931-N Series Low Dropout Regulators Check for Samples: LM2931-N FEATURES 1 2 Very Low Quiescent Current Output Current in Excess of 100 mA Input-output Differential Less than 0.6V Reverse Battery Protection 60V Load Dump Protection −50V Reverse Transient Protection Short Circuit Protection Internal Thermal Overload Protection Mirror-image Insertion Protection Available in TO-220, TO-92, TO-263, or SOIC-8 Packages Available as Adjustable with TTL Compatible Switch DESCRIPTION The LM2931-N 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-N 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-N 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 input voltage to the regulator can momentarily exceed the specified maximum operating voltage, the regulator will automatically shut down to protect both internal circuits and the load. The LM2931-N cannot be harmed by temp...
