RT9010 300mA LDO Regulator with POR 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 www.DataSheet4U.com for battery-power devices. Other features include current limiting, over temperature, output short circuit protection. RT9010 is short circuit thermal folded back protected. RT9010 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. RT9010 can operate stably with very small ceramic output capacitors, reducing required board space and component cost. RT9010 is available in fixed output voltages in the TSOT-23-6 package.
