RT9011 Datasheet, PDF (1/12 Pages) Richtek Technology Corporation – Portable Power Management 300mA Dual LDO Regulator

Preliminary
RT9011
Portable Power Management 300mA Dual LDO Regulator
General Description
Features
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.
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.
RT9011 is short circuit thermal folded back protected.
RT9011 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.
RT9011 can operate stably with very small ceramic output
capacitors, reducing required board space and component
cost. RT9011 is available in fixed output voltages in the
TSOT-23-6 and WDFN-8L 2x2 package.
