4 / 5 page Typical Performance Characteristics (Continued) 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, 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 com- ponents. 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 regula- tion.

Locate as close as possible to the regulation. DS009306-6 Note: Compared to IC regulator with 2.0V dropout voltage and IQmax, = 6.0 mA. www.national.com 4 |
