RT9037
300mA, Low Noise, Ultra-Fast CMOS LDO Regulator
General Description
The RT9037 is designed for portable RF and wireless
applications with demanding performance and space
requirements. The RT9037 performance is optimized for
battery-powered systems to deliver ultra low noise and
low quiescent current. Regulator ground current increases
only slightly in dropout, further prolonging the battery life.
The RT9037 also works with low-ESR ceramic capacitors,
reducing the amount of board space necessary for power
applications, critical in hand-held wireless devices. The
RT9037 consumes less than 0.01uA in shutdown mode
and has fast turn-on time less than 50us. 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 package, the RT9037 also offers
a wide output voltage range from 3.3V to 5V with 0.1V per
step.
