RTQ2522B Overview
The RTQ2522A/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 es directly f rom the VIN supply f or high ef f iciency regulation.
