Preliminary
RT9016
500mA Peak, Thermal Folded Back CMOS LDO Regulator
General Description
The RT9016 is designed for portable RF and wireless
applications with demanding performance and space
requirements. The RT9016 performance is optimized for
battery-powered systems to deliver ultra low noise and
low quiescent current. A noise bypass pin is available for
www.DataShfueretth4eUr.croemduction of output noise. Regulator ground current
increases only slightly in dropout, further prolonging the
battery life. The RT9016 also works with low-ESR ceramic
capacitors, reducing the amount of board space necessary
for power applications, critical in hand-held wireless
devices. The RT9016 consumes less than 0.01μA in
shutdown mode and has fast turn-on time less than 50μs.
RT9016 is short circuit thermal folded back protected.
RT9016 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-23-5 and WDFN-6L 2x2 packages.
