Preliminary
RT9012
300mA Dual LDO Regulator with POR
General Description
Features
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 3.6V
by operating from 2.5V to 5.5V input.
RT9012 offers 2% accuracy, extremely low dropout voltage
www.DataSh(2ee4t04mU.cVom@ 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.
RT9012 is short circuit thermal folded back protected.
RT9012 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.
RT9012 can operate stably with very small ceramic output
capacitors, reducing required board space and component
cost. RT9012 is available in fixed output voltages in the
WDFN-8L 2x2 package.

Note 1. Stresses listed as the above "Absolute Maximum Ratings" may cause permanent damage to the device. These are for
stress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended
periods may remain possibility to affect device reliability.
Note 2. Devices are ESD sensitive. Handling precaution recommended.
Note 3. The device is not guaranteed to function outside its operating conditions.
Note 4. θJA is measured in the natural convection at TA = 25°C on a low effective thermal conductivity test board of
JEDEC 51-3 thermal measurement standard.
Note 5. The dropout voltage is defined as VIN -VOUT, which is measured when VOUT is VOUT(NORMAL) − 100mV.
