RT9030
150mA, Low Input Voltage, Low Dropout, Low Noise Ultra-
Fast Without Bypass Capacitor CMOS LDO Regulator
General Description
The RT9030 is a high-performance, 150mA LDO regulator,
offering extremely high PSRR and ultra-low dropout. Ideal
for portable RF and wireless applications with demanding
performance and space requirements.
The RT9030 quiescent current as low as 25μA, further
prolonging the battery life. The RT9030 also works with
low-ESR ceramic capacitors, reducing the amount of board
space necessary for power applications, critical in hand-
held wireless devices.
The RT9030 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-70-5 and WDFN-6L 1.6x1.6 package.
