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 further reduction 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.
