Ordering Information
High Voltage, Low Quiescent, 60mA LDO Regulator
General Description
The RT9022 is designed for positive CCD bias applications
with critical performance and space requirements. The
RT9022 performance is optimized for battery-powered
systems to deliver low noise and low quiescent current
and with soft start function.
The RT9022 also works well with low-ESR ceramic
capacitors, reducing the amount of board space necessary
for power applications and consumes less than 1
μA in
shutdown mode.
The other features include ultra low dropout voltage, high
output accuracy, and current limiting protection. The part
is available in the SOT-23-6, TSOT-23-6 and SC-70-6
packages.
