Preliminary

RT9017

500mA Peak, Thermal Folded Back CMOS LDO Regulator

General Description

Features

^zShort Circuit Thermal Folded Back Protection

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 (V_OUT< 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.
