RT9055

300mA Dual LDO Regulator

RT9055
New

The RT9055 is a dual channel, low noise, and low dropout regulator sourcing up to 300mA at each channel. The output voltage range is from 0.9V to 3.5V with an input voltage range from 1.5V to 5.5V.
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.
The RT9055 allows stable operation with very small ceramic output capacitors, hence minimizing required board space and component cost.
The RT9055 is available in a WL-CSP-6B 0.8x1.2 package.
