® RTQ2527A/B 2A Ultra-Low Dropout Voltage LDO Regulators with Soft-Start General Description The RTQ2527A/B is a very low dropout linear regulator which operates from input voltage as low as 0.8V. The device is capable of supplying 2A of output current with a typical dropout voltage of only 100mV. 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 regulation. User-programmable 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 flexibility provides an easy-to-use robust power management solution for a wide variety of applications.
