RT9020
500mA, Low Dropout, Low Noise Ultra-Fast With Soft Start
CMOS LDO Regulator
General Description
The RT9020 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 RT9020 quiescent current is as low as 25μA, further
prolonging the battery life. The RT9020 also works with
low-ESR ceramic capacitors, reducing the amount of board
space necessary for power applications, critical in hand-
held wireless devices.
The RT9020 consumes typical 0.7μA in shutdown mode
and has fast turn-on time less than 70μs (without C
SS
).
The other features include ultra-low dropout voltage, high
output accuracy, current limiting protection, and high ripple
rejection ratio. Tiny packages SOT-23-5 and SC-70-5 are
available.
Features
Wide Operating Voltage Ranges : 2.2V to 5.5V
