The RT9004 is designed for portable RF and wireless
applications with demanding performance and space
requirements. The RT9004 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 RT9004 also works with low-ESR ceramic capacitors,
reducing the amount of board space necessary for power
applications, critical in hand-held wireless devices. The
RT9004 consumes less than 0.01uA in shutdown mode
and has fast turn-on time less than 50us. RT9004 is short
circuit thermal folded back protected. RT9004 lowers its
OTP trip point from 165°C to 110°C when output short
circuit occurs (VOUT < 0.4V) providing maximum safety to
end users. The other features include ultra low dropout
voltage, high output accuracy, current limiting protection,
and high ripple rejection ratio. Available in the VDFN-10L
3x3 and WDFN-10L 3x3 packages, the RT9004 also offers
custom voltage, range of 1.5V to 3.5V with 0.1V per step.
