General Description

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.

The RT9012 offers 2% accuracy, extremely low dropout

voltage (240mV @ 300mA), and extremely low ground

current, only 27uA 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.

Note :

Richtek products are :

RoHS compliant and compatible with the current require-

ments of IPC/JEDEC J-STD-020.

Suitable for use in SnPb or Pb-free soldering processes.
