Preliminary
RT9013
500mA, Low Dropout, Low Noise Ultra-Fast Without
Bypass Capacitor CMOS LDO Regulator
General Description
Features
ꢀ Wide Operating Voltage Ranges : 2.2V to 5.5V
The RT9013 is a high-performance, 500mALDO regulator,
offering extremely high PSRR and ultra-low dropout. Ideal
for portable RF and wireless applications with demanding
performance and space requirements.
ꢀ Low Dropout : 250mV at 500mA
ꢀ Ultra-Low-Noise for RF Application
ꢀ Ultra-Fast Response in Line/Load Transient
ꢀ Current Limiting Protection
The RT9013 quiescent current as low as 25μA, further
prolonging the battery life. The RT9013 also works with
low-ESR ceramic capacitors, reducing the amount of board
space necessary for power applications, critical in hand-
held wireless devices.
ꢀ Thermal Shutdown Protection
ꢀ High Power Supply Rejection Ratio
ꢀ Output Only 1μF Capacitor Required for Stability
ꢀ TTL-Logic-Controlled Shutdown Input
ꢀ RoHS Compliant and 100% Lead (Pb)-Free
The RT9013 consumes typical 0.7μA in shutdown mode
and has fast turn-on time less than 40μs. The other features
include ultra-low dropout voltage, high output accuracy,
current limiting protection, and high ripple rejection ratio.
Available in the SOT-23-5, SC-70-5 and WDFN-6L 2x2
package.
