RT9011MMPJ6 是一款双路300mA输出，低噪声，低压差的线性稳压器。输出电压范围为1.2V到3.6V,输入电压为2.5V到5.0V.常用于手机，手提电脑，PCMCIA卡及其他电池供电产品的电源电路中。

The RT9011MMPJ6 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 3.6V by operating from 2.5V to 5.5V input.
The RT9011MMPJ6 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 RT9011MMPJ6 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 RT9011MMPJ6 can operate stably with very small ceramic output capacitors, reducing required board space and component cost. The RT9011MMPJ6 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.
