ME1117 Datasheet PDF – 1A Low Dropout Voltage Regulator

Part Number: ME1117

Function : 1A Low Dropout Voltage Regulator

Package: SOT-223, TO-252 and TO-263 package available

Manufacturer: Matsuki Electric


ME1117 voltage regulator


The ME1117 series of adjustable and fixed voltage regulators are designed to provide 1A output current and to operate down to 1A input-to-output differential. The dropout voltage of the device is guaranteed maximum 1.3V at maximum output current, decreasing at lower load currents.

On-Chip trimming adjusts the reference voltage to 1%. Current limit is also trimmed, minimizing the stress under overload conditions on both the regulator and power source circuitry.
