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.
