Preliminary  
RT9011  
Portable Power Management 300mA Dual LDO Regulator  
General Description  
Features  
z Wide Operating Voltage Ranges : 2.5V to 5.5V  
The RT9011 is a dual channel, low noise, and low dropout  
regulator sourcing up to 300mAat each channel. The range  
of output voltage is from 1.2V to 3.6V by operating from  
2.5V to 5.5V input.  
z Low-Noise for RF Application  
z No Noise Bypass Capacitor Required  
z Fast Response in Line/Load Transient  
z TTL-Logic-Controlled Shutdown Input  
z Low Temperature Coefficient  
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.  
z Dual LDO Outputs (300mA/300mA)  
z Ultra-low Quiescent Current 27μA/LDO  
z High Output Accuracy 2%  
z Short Circuit Protection  
z Thermal Shutdown 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.  
z Current Limit Protection  
z Short Circuit Thermal Folded Back Protection  
z Tiny TSOT-23-6 and 8-Lead WDFN Package  
z RoHS Compliant and 100% Lead (Pb)-Free  
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.  
Applications  
z CDMA/GSM Cellular Handsets  
z Battery-Powered Equipment  
z Laptop, Palmtops, Notebook Computers  
z Hand-Held Instruments
