Key features

` High power supply ripple rejection (PSRR)

` Very low quiescent current (30 μA) and low noise (50 μVrms)

` Small package size

Key benefits

` Very small package for mobile application

` Very low standby and supply current for battery-powered

solutions

` No additional noise bypass capacitor needed

Key applications

` Mobile phones, tablet PCs, DSCs (digital still cameras), video

cameras, game pads, notebooks, netbooks, ultrabooks

High-PSSR LDO with soft-start

` Soft-start guarantees a constant start-up time

` Limits the inrush current

` Prevents unwanted input voltage dip

` Ensures defined start-up behavior
