Low Dropout Voltage: 1.1V Typ. at IOUT =1A On-chip Thermal Limiting: 150°C Typ. Adjustable Output: 1.25~10.7V Standard 3-pin SOT-223 and TO252 Power Packages EP1117 1A Low Dropout Linear Regulator Description The EP1117 is a low dropout three-terminal adjustable or fixed-voltage regulator with 1A output current capability. The EP1117 is available in an adjustable version, with output ranging from 1.25V to 10.7V and fixed output voltages of 1.8V, 2.5V, 3.3V and 5.0V. Dropout voltage is guaranteed at a maximum of 1.3V at 1A. On-chip thermal limiting provides protection against any combination of overload that would create excessive junction temperatures. The EP1117 is available in the industry standard 3-pin the low profile surface mount SOT-223 and TO-252 power packages.
