RTQ2527D 3A Ultra-Low Dropout Voltage Regulators

The RTQ2527D is a very low-dropout linear regulator which operates from input voltage as low as 0.8V. The device is capable of supplying 3A of output current with a typical dropout voltage of only 120mV. A VBIAS supply is required to run the internal reference and LDO circuitry while output current comes directly from the VIN supply for high efficiency regul.
