RT9198T

Pinout




Description

The RT9198T is designed for portable RF and wireless applications with demanding performance and space requirements. The RT9198T 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 RT9198T also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The RT9198T consumes less than 0.01uA in shutdown mode and has fast turn-on time less than 50ms. RT9198T is short circuit thermal folded back protected. RT9198T 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 SC-70-5 packages, the RT9198T also offers a range of 1.5V to 3.5V with 0.1V per step.
