1FEATURES DESCRIPTIONThe LM2931-N positive voltage regulator featuresa
Very Low Quiescent Current very low quiescent current of 1mA or less when
• Output Currentin Excessof 100 mA supplying 10mA loads. This unique characteristic and
Input-output Differential Less than 0.6V the extremely low input-output differential required for
proper regulation (0.2V for output currentsof 10mA)
• Reverse Battery Protection make the LM2931-N the ideal regulator for standby
• 60V Load Dump Protection power systems. Applications include memory standby
• −50V Reverse Transient Protection circuits, CMOS and other low power processor power
supplies as well as systems demanding as much as
• Short Circuit Protection 100mAof output current.
• Internal Thermal Overload ProtectionDesigned originally for automotive applications, the
• Mirror-image Insertion Protection LM2931-N and all regulated circuitry are protected
• Availablein TO-220, TO-92, TO-263,or SOIC-8 from reverse battery installationsor2 battery jumps.
Packages During line transients, such asa load dump (60V)
Available as Adjustable with TTL Compatible when the input voltage to the regulator can
Switch momentarily exceed the specified maximum
operating voltage, the regulator will automatically shut
downto protect both internal circuits and the load.
The LM2931-N cannot be harmed by temporary
mirror-image insertion. Familiar regulator features
suchas short circuit and thermal overload protection
are also provided.
The LM2931-N family includesa fixed 5V output
(±3.8% toleranceforA grade)oran adjustable output
with ON/OFF pin. Both versions are availableina
TO-220 power package, DDPAK/TO-263 surface
mount package, and an 8-lead SOIC package. The
fixed output versionis also availablein the TO-92
plastic package.
