DESCRIPTION
The LM330-N 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.
The low dropout voltage makes the LM330-N useful
for certain battery applications since this feature
allows a longer battery discharge before the output
falls out of regulation. For example, 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-N
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 damaging internal and external circuits.
Also, the LM330-N regulator cannot be harmed by a
temporary mirror-image insertion.

TYPICAL APPLICATIONS
The LM330-N 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-N can operate at a much lower input voltage, the device
power dissipation is reduced, heat sinking can be simpler and device reliability improved through lower chip
operating temperature. Also, a cost savings can be utilized through use of lower power/voltage components. In
applications utilizing battery power, the LM330-N allows the battery voltage to drop to within 0.3V of output
voltage prior to the voltage regulator dropping out of regulation.
* 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 ensure
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.
Note: Compared to IC regulator with 2.0V dropout voltage and IQmax, = 6.0 mA.
