The RT9017 is designed for portable RF and wireless
applications with demanding performance and space
requirements. The RT9017 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 RT9017 also works with low-ESR ceramic capacitors,
reducing the amount of board space necessary for power
applications, critical in hand-held wireless devices. The
RT9017 consumes less than 0.01μA in shutdown mode
and has fast turn-on time less than 50μs. RT9017 is short
circuit thermal folded back protected. RT9017 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 SOT-23-3,
SOT-23-5 and WDFN-6L 2x2 packages, the RT9017 also
offers a range of 1.5V to 3.5V with 0.1V per step.
