LM330
3-Terminal Positive Regulator
General Description
aging internal and external circuits. Also, the LM330 regula-
tor cannot be harmed by a temporary mirror-image insertion.
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 protection are
also provided.
Features
n Input-output differential less than 0.6V
n Output current of 150 mA
n Reverse battery protection
n Line transient protection
n Internal short circuit current limit
n Internal thermal overload protection
n Mirror-image insertion protection
n P+ Product Enhancement tested
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
inputs resulting from reverse installations of batteries.
Other protection features include line transient protection up
to 26V, when the output actually shuts down to avoid dam-

heat sinking can be simpler and device reliability improved
through lower chip operating temperature. Also, a cost sav-
ings can be utilized through use of lower power/voltage
components. In applications utilizing battery power, the
LM330 allows the battery voltage to drop to within 0.3V of
output voltage prior to the voltage regulator dropping out of
regulation.
Typical Applications
The LM330 is designed specifically to operate at lower input
to output voltages. The device is designed utilizing a power
lateral PNP transistor which reduces dropout voltage from
2.0V to 0.3V when compared to IC regulators using NPN
pass transistors. Since the LM330 can operate at a much
lower input voltage, the device power dissipation is reduced,

* Required if regulator is located far from power supply filter.
** C2 may be either an Aluminum or Tantalum type capacitor but must be rated to operate at −40˚C to guarantee regulator stability to that temperature extreme.
10 µF is the minimum value required for stability and may be increased without bound. Locate as close as possible to the regulation.
