RT9186A/B
Low Profile 500mA LDO with Enable and Power Good/Reset
General Description
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.
