MT1118
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
