RT9012

300mA Dual LDO Regulator with POR

RT9012
New

RT9012 is a dual channel, low noise, and low dropout with the sourcing ability up to 300mA and power-on reset function. The range of output voltage is from 1.2V to 3.5V by operating from 2.5V to 5.5V input. The RT9012 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 RT9012 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 RT9012 can operate stably with very small ceramic output capacitors, reducing required board space and component cost. The RT9012 is available in fixed output voltages in the WDFN-8L 2x2 package.
