RT9055

300mA Dual LDO Regulator

General Description

Features

^Wide Operating Voltage Range : 1.5V to 5.5V

The RT9055 is a dual channel, low noise, and low dropout

regulator sourcing up to 300mAat each channel. The output

voltage range is from 0.9V to 3.5V with an input voltage

range from 1.5V to 5.5V.

^Low Noise for RF Application

^No Noise Bypass Capacitor Required

^Fast Response in Line/Load Transient

^TTL Logic Controlled Shutdown Input

^Low Temperature Coefficient

The RT9055 offers 2% accuracy, extremely low dropout

voltage and extremely low quiescent current (only 29μA

per LDO). The shutdown current is near zero which is

suitable for battery powered applications. The RT9055 also

provides protection functions such as current limiting,

output short circuit protection, and over temperature

protection.

^Dual LDO Outputs (300mA/300mA)

^Ultra-Low Quiescent Current : 29μA/LDO

^High Output Accuracy 2%

^Short Current Protection

^Thermal Shutdown Protection

^Current Limit Protection

The RT9055 allows stable operation with very small

ceramic output capacitors, hence minimizing required

board space and component cost.

 Short Circuit Thermal Folded Back Protection

 RoHS Compliant and Halogen Free

Applications

The RT9055 is available in a WL-CSP-6B 0.8x1.2 package.
