500mA, Low Dropout, Low Noise Ultra-Fast Without
Bypass Capacitor CMOS LDO Regulator
RT9013
General Description
The RT9013 is a high-performance, 500mA LDO regulator,
offering extremely high PSRR and ultra-low dropout. Ideal
for portable RF and wireless applications with demanding
performance and space requirements.
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.
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 SC-82, SOT-23-5, SC-70-5 and WDFN-6L
2x2 package.

Note 1. Stresses listed as the above “Absolute Maximum Ratings” may cause permanent damage to the device. These are for
stress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the operational
sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may
remain possibility to affect device reliability.
