RT9081A

500mA, 5.5V, Ultra Low Dropout Linear Regulator

General Description

Features

^Input Voltage Range : 0.8V to 5.5V

^Bias Voltage Range : 2.4 V to 5.5 V

^Output Voltage Fixed and Adjustable Versions

^0.9V to 1.8V (Fixed)

The RT9081A is a high performance positive voltage

regulator with separated bias voltage (V_BIAS), designed

for applications requiring low input voltage and ultra low

dropout voltage, output current up to 500mA. The feature

of ultra low dropout voltage is ideal for applications where

output voltage is very close to input voltage. The input

voltage can be as low as 0.8V and the output voltage is

adjustable by an external resistive divider. The RT9081A

features very low quiescent current consumption for

portable applications. The device is available in the ZADFN-

6L 1.2x1.2 package.

^0.8V to 3.6V (Adjustable)
