RT9085A

1A, 5.5V, Ultra Low Dropout Linear Regulator

General Description

Features

^Input Voltage Range : 0.8V to 5.5V

^Bias Voltage Range : 3V to 5.5V

^Available in Fixed and Adjustable (0.5V to 3V)

^Ultra Low Dropout Voltage : 60mV at 1A

^Accurate Output Voltage Accuracy (1%) Over Line,

Load @ 25°C

The RT9085A 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 1A. 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 RT9085A

features very low quiescent current consumption for

portable applications. The device is available in the WL-

CSP-6B 0.8x1.2 (BSC) package.
