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.
