LM330
3-Terminal Positive Regulator
General Description
The LM330 5V 3-terminal positive voltage regulator features
an ability to source 150 mA of output current with an
input-output differential of 0.6V or less. Familiar regulator
features such as current limit and thermal overload protec-
tion are also provided.
The low dropout voltage makes the LM330 useful for certain
battery applications since this feature allows a longer battery
discharge before the output falls out of regulation. For ex-
ample, a battery supplying the regulator input voltage may
discharge to 5.6V and still properly regulate the system and
load voltage. Supporting this feature, the LM330 protects
both itself and regulated systems from negative voltage in-
puts resulting from reverse installations of batteries.
Other protection features include line transient protection up
to 26V, when the output actually shuts down to avoid damag-
ing internal and external circuits. Also, the LM330 regulator
cannot be harmed by a temporary mirror-image insertion.
