DESCRIPTION

The MT1118 series is a low-drop-out ( LDO ) linear regulator. The devices have been optimized for applications where fast transient response and minimum input voltages are critical. At light loads the typical dropout voltage is 10mV, and at full load the maximum dropout voltage is less than 500mV. The internal over-current protection and thermal protection ,makes the device extremely easy to use in a wide range of applications. ◆ APPLICATIONS * Active SCSI terminators * Battery charges * High efficiency linear regulators * Wireless communication systems * Digital camera ◆ FEATURES * Low dropout performance * Output current of 500mA/300mA typical * Thermal shutdown protection voltages available * SOT-89 packages available , SOT-23 and SOT-23-5 SOT-89 (Top View) SOT-23 (Top View) VREF3 E L E C T R O N I C MT1118

Exceeding the maximum allowable power disspation will result in excessive die temperature, and the regulator will go into thermal shutdown. 2.TJ: Junction Temperature Calculation: T J = TA + (PD × θJA) The θJA numbers are guidelines for the thermal performance of the device/PC-board system. All of the above assume no ambient airflow. 3.θJA: Thermal Resistance-Junction to Ambient, DF : Derating factor, Po: Power consumption. 4.θJT: Thermal Resistance-Junction to Ambient, TC: case(Tab) temperature, TJ = TC + (PD × θJT) for S package. ◆ RECOMMENDED OPERATING CONDITIONS: Recommended Operating Symbol Parameter Min.
