LM2930

3-Terminal Positive Regulator

General Description

The LM2930 3-terminal positive regulator features an ability

to source 150 mA of output current with an input-output

differential of 0.6V or less. Efficient use of low input voltages

obtained, for example, from an automotive battery during

cold crank conditions, allows 5V circuitry to be properly

powered with supply voltages as low as 5.6V. Familiar regu-

lator features such as current limit and thermal overload

protection are also provided.

Designed originally for automotive applications, the LM2930

and all regulated circuitry are protected from reverse battery

installations or 2 battery jumps. During line transients, such

as a load dump (40V) 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 LM2930 cannot be

harmed by temporary mirror-image insertion.

Fixed outputs of 5V and 8V are available in the plastic

TO-220 and TO-263 power packages.
