E L E C T R O N I MT1118 C 1A LDO LINEAR VOLTAGE / REGULATORS ◆ 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. ◆ ◆ FEATURES * Low dropout performance * Output current of 500mA/300mA typical * Thermal shutdown protection * Fixed 1.5V/ 1.8V/ 2.5V/ 2.8V/ 3.0V/ 3.3V output voltages available * SOT-89 packages available , SOT-23 and SOT-23-5 APPLICATIONS * Active SCSI terminators * Battery charges * High efficiency linear regulators * Wireless communication systems * Digital camera ◆ PIN CONFIGURATIONS SOT-89 SOT-23 (Top View) (Top View) 2 3 VREF 1 1 2 3 *MT11182-X.XJ 1: GND, 2: IN, 3: OUT *MT11181-X.XJ 1: OUT, 2: GND, 3: IN *2Y 1: GND, 2: OUT, 3: IN *1Y 1: OUT, 2: IN, 3: GND Note: Y (Output Voltage) A: VOUT=1.5V, D: VOUT=2.8V, B: VOUT=1.8V, C: VOUT=2.5V E: VOUT=3.0V, F: VOUT=3.3V http:// www.sirectsemi.com -1- MT1118 ◆ ABSOLUTE MAXTMUM RETINGS SYMBOL PARAMETER VIN Input supply voltage θJA Thermal resistance junction to ambient SOT-89 SOT-23 & SOT-23-5 MAXIMUM UNITS 6 V O 71 230 C/W O TJ Operating junction temperature range 150 C O TSTG Storage temperature range - 65 to 150 C O TLEAD Lead temperature (soldering) 10sec 260 C Note 1: Exceeding these ratings could cause damage to the device.
