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 dif-
ferential 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 pow-
ered with supply voltages as low as 5.6V. Familiar regulator
features such as current limit and thermal overload protec-
tion 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.
