RT9014/A is a dual channel, low noise, and low dropout with the sourcing ability up to 300mA, an open drain driver and power-on reset function. The open-drain output is capable of sinking 150mA for LED backlighting applications.

The range of output voltage is from 1.2V to 3.5V by operating from 2.5V to 5.5V input.

The RT9014/A offers 2% accuracy, extremely low dropout voltage (240mV @ 300mA), and extremely low ground current, only 27μA per LDO. The shutdown current is near zero current which is suitable for battery-power devices. Other features include current limiting, over temperature, output short circuit protection.

The RT9014/A is short circuit thermal folded back protected. The IC lowers its OTP trip point from 165°C to 110°C when output short circuit occurs (VOUT < 0.4V) providing maximum safety to end users.

The RT9014/A can operate stably with very small ceramic output capacitors, reducing required board space and component cost. The RT9014/A is available in fixed output voltages in the WDFN-10L 3x3 package.
