RT9013B
300mA, Low Dropout, Low Noise Ultra-Fast Without
Bypass Capacitor CMOS LDO Regulator
General Description
The RT9013B is a high-performance, 300mA LDO regulator,
offering extremely high PSRR and ultra-low dropout. The
RT9013B is Ideal for portable RF and wireless applications
with demanding performance and space requirements.
The RT9013B provides quiescent current to be as low as
25uA to extend the battery life. The RT9013B also works
with low-ESR ceramic capacitors, reducing the amount of
board space necessary for power applications, especially
for hand-held wireless devices.
Features
Wide Operating Voltage Range : 2.2V to 5.5V
Low Dropout : 150mV at 300mA
Ultra-Low-Noise for RF Application
Ultra-Fast in Line/Load Transient Response
Current Limiting Protection
Thermal Shutdown Protection
High Power Supply Rejection Ratio
Only 1uF Output Capacitor Required for Stability
TTL-Logic-Controlled Shutdown Input
RoHS Compliant and 100% Lead (Pb)-Free
The RT9013B consumes typical 0.7uA in shutdown mode
and has fast turn-on time to be less than 40us. The other
features include ultra-low dropout voltage, high output
accuracy, current limiting protection, and high ripple
rejection ratio. The RT9013B is available in the SC-70-5
and WDFN-6L 1.6x1.6 packages.
