RT9186AGF Datasheet, PDF (1/13 Pages) Richtek Technology Corporation – 2.5V to 5.5V Wide Input Range, Guaranteed 500mA Output Current

®
RT9186A/B
Low Profile 500mA LDO with Enable and Power Good/Reset
General Description
Features
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.
z 2.5V to 5.5V Wide Input Range
z Guaranteed 500mA Output Current
z Low 160mV Dropout at 500mA
z 1.8V/2.5V/3.3V Preset Output Voltage Version with
Adjustable Range from 0.8V to 4.5V.
z Reset Output with 6ms (typ.) Delay Time
z Power Good Output
z Low 190μA Ground Pin Current

z RoHS Compliant and 100% Lead (Pb)-Free
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.
