RT9011

Portable Power Management 300mA Dual LDO Regulator

RT9011
New

The RT9011 is a dual channel, low noise, and low dropout regulator sourcing up to 300mA at each channel. The range of output voltage is from 1.2V to 3.5V by operating from 2.5V to 5.5V input. The RT9011 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 RT9011 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 RT9011 can operate stably with very small ceramic output capacitors, reducing required board space and component cost. The RT9011 is available in fixed output voltages in the TSOT-23-6, WDFN-8L 2x2, WDFN-10L 3x3, WDFN-8L 3x3 and WDFN-6L 1.6x1.6 packages.
