概述
The LP3996 is a low-dropout voltage regulator with low quiescent current and in ultra-small package. The LP3996 can deliver output current up to 250mA. It offers different output voltages without external resistors. For the nominal output voltage, 1.2V, 1.8V, 3.0V and 3.3V will be available. The LP3996 is integrated over current protection and short circuit protection in order to protect system abnormal. The output capacitor as small as 0.1µF is good enough for LP3996. The LP3996 is available in 3 pins SOT23 package or 4 pins ultra-small TDFN package with only 1mm 1mm size.
