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 regulator 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 SFM power packages.
