General Description
The RT9011 is a dual channel, low noise, and low dropout
regulator sourcing up to 300mA at each channel. The range
of output voltage is from 1.2V to 3.6V by operating from
2.5V to 5.5V input.
The RT9011 offers 2% accuracy, extremely low dropout
voltage (240mV @ 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.
The RT9011 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 RT9011 can operate stably with very small ceramic
output capacitors, reducing required board space and
component cost. The RT9011 is available in fixed output
voltages in the TSOT-23-6, WDFN-8L 2x2, WDFN-10L 3x3,
WDFN-8L 3x3 and WDFN-6L 1.6x1.6 packages.
