MT1118

E L E C T R O N I C 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.
