RT9008GE

The RT9008GE from Richtek is a low dropout linear regulator controller with soft-start in 6 pin SOT-23 package. This is a wide input range, low dropout voltage regulator controller with soft-start function. The part drives an external N-MOSFET and can operate with VCC power range from 4.5V to 13.5V. With this flexible topology and wide input voltage range the RT9008 is suitable for various applications. The soft-start function can reduce the input inrush current by adjusting the external capacitor. It is used in desktop/notebook PC, DSC and processor power sequencing.
