LP2206
2×600mA,Dual Channel Ultra-Fast CMOS LDO Regulator
概述
The LP3991 is a low-dropout voltage regulator with low quiescent current and ultra-small packages. The LP3991 can deliver output current up to 250mA. The device offers different fixed output voltages without external resistors, for the nominal output voltage. The LP3991 integrated current limit protection and short circuit protection and thermal shutdown protection in order to protect system abnormal. The output capacitor as small as 0.1µF is available for LP3991 application. The LP3991 is available in SOT23 package andultra-small TDFN-4 package with only 1mm 1mm size.
