522A/B is a very low dropout linear regulator which operates f rom input voltage as low as 0.8V. The device is capable of supplying 2A of output current with a typical dropout voltage of only 90mV. A VBIAS supply is required to run the internal ref erence and LDO circuitry while output current comes directly f rom the VIN supply f or high ef f iciency regulation. Userprogrammable soft-start limits the input inrush current and minimizes stress on the input power. The enable input and power good output allow easy sequencing with external regulators. This complete f lexibility provides an easy-to-use robust power management s
