概述
The LPQ3988 is a low-dropout voltage regulator with very low noise and high PSRR in a small package for automotive application. The LPQ3988 can deliver output current up to 600mA. The output voltage could be selected to 1.8V, 2.8V, and 3.3V.The LPQ3988 integrated over current protection and thermal shutdown in order to protect system abnormal.The input and output capacitor as small as 1µF will be good enough for LPQ3988.The LPQ3988 is available in normal SOT23-5 package.
