RT9013A
120mA, Low Dropout, Low Noise Ultra-Fast Without
Bypass Capacitor CMOS LDO Regulator
General Description
The RT9013A is a high-performance, 120mA LDO regulator,
offering extremely high PSRR and ultra-low dropout. The
chip is ideal for portable RF and wireless applications with
demanding performance and space requirements.
The RT9013A provides quiescent current to be as low as
25uA to extend the battery life. The RT9013A 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 Ranges : 2.2V to 5.5V
Low Dropout : 60mV at 120mA
Ultra-Low-Noise for RF Application
Ultra-Fast Response in Line/Load Transient
Current Limiting Protection
Thermal Shutdown Protection
High Power Supply Rejection Ratio
Output Only 1uF Capacitor Required for Stability
TTL-Logic-Controlled Shutdown Input
RoHS Compliant and 100% Lead (Pb)-Free
The RT9013A consumes typical 0.7uA in shutdown mode
and has fast turn-on time less than 40us. The other features
include ultra-low dropout voltage, high output accuracy,
current limiting protection, and high ripple rejection ratio.
Available in the SC-70-5 and SC-82 packages.
