MT1117
1A LDO LINEAR VOLTAGE / REGULATORS
◆
DESCRIPTION
◆
The MT1117 series are low-drop-out ( LDO ) linear
regulators. The devices have been optimized
for applications where fast transient response and
minimum input voltages are critical. 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 800mA typical
* Wide range input supply voltage
* Thermal shutdown protection
* Fixed 1.8V, 2.5V, 3.3V output voltages available
* SOT-223 packages available
APPLICATIONS
* Active SCSI terminators
* High efficiency linear regulators
* Motherboard clock supplies
