Hot-selling and scarce RT9186AGQV 2.5V to 5.5V Wide Input Range, Guaranteed 500mA Output Current QFN spot stock
RT9186AGQV 2.5V to 5.5V Wide Input Range, Guaranteed 500mA Output Current QFN spot stock
Product Descriptions
The RT9186 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 RT9186 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. RT9186A contains PGOOD function. On the other hand, RT9186B contains RST function with 6ms (typ.) time delay.
