LPSemi/微源半导体 LPQ3988H SOT23-5 汽车超低噪声和高PSRR LDO
Description
The LPQ3988H is a low-dropout voltage regulator with verylow noise and high PSRR in a small package forautomotive application. The LPQ3988H can deliver outputcurrent up to 600mA. The output voltage could be selectedto 1.8V, 2.8V, and 3.3V.
The LPQ3988 integrated over current protection andthermal shutdown in order to protect system abnormal.The input and output capacitor as small as 1μF will begood enough for LPQ3988.
The LPQ3988 is available in normal SOT23-5 package.
