RT9186AGQV Product Details

The RT9186AGQV is a low-dropout linear regulator providing up to 500mA load current with 160mV dropout. It is especially designed for the application of portable and smart handheld device. The RT9186AGQV operates from 2.5V to 5.5V supply. The internal P-MOSFET pass transistor allows the regulator to work with 190μA low quiescent current. Its preset output voltage version covers the most frequently used values, including 1.8V/2.5V/3.3V. Output voltage can also be adjusted via the ADJ pin for those other than the preset values. With only 0.1μA required in the shut down mode, one enable pin is able to control output on/off. The RT9186AGQV contains PGOOD function.
