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
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.
