Preliminary  
RT9004  
300mA, Low Noise, Ultra-Fast CMOS Triple LDOs Regulator  
General Description  
Features  
z Short Circuit Thermal Folded Back Protection  
The RT9004 is designed for portable RF and wireless  
applications with demanding performance and space  
requirements. The RT9004 performance is optimized for  
battery-powered systems to deliver ultra low noise and  
low quiescent current. Regulator ground current increases  
only slightly in dropout, further prolonging the battery life.  
The RT9004 also works with low-ESR ceramic capacitors,  
reducing the amount of board space necessary for power  
applications, critical in hand-held wireless devices. The  
RT9004 consumes less than 0.01uA in shutdown mode  
and has fast turn-on time less than 50us. RT9004 is short  
circuit thermal folded back protected. RT9004 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 other features include ultra low dropout  
voltage, high output accuracy, current limiting protection,  
and high ripple rejection ratio. Available in the VDFN-10L  
3x3 and WDFN-10L 3x3 packages, the RT9004 also offers  
custom voltage, range of 1.5V to 3.5V with 0.1V per step.
