General Description

RT9010 is a 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.

RT9010 offers 2 accuracy, extremely low dropout voltage (240mV @ 300mA), and extremely low ground current. 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.
