GENERAL DESCRIPTION

FEATURES

Regulator ground current increases z < 0.01uA Standby Current When Shutdown only slightly in dropout, further prolonging the battery life. z Low Dropout : 220mV @ 300mA The RT9198T also works with low-ESR ceramic capacitors, z Wide Operating Voltage Ranges : 2.5V to 5.5V reducing the amount of board space necessary for power z TTL-Logic-Controlled Shutdown Input applications, critical in hand-held wireless devices. RT9198T is short circuit thermal folded back protected. RT9198T lowers its z Thermal Shutdown Protection z Only 1uF Output Capacitor Required for Stability 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 z High Power Supply Rejection Ratio z Custom Voltage Available z RoHS Compliant and 100% Lead (Pb)-Free 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.
