Low Dropout Fast Response Positive Adjustable Regulator

www.DataSheet4U.com AT1117 Preliminary Product Information 1A Low Dropout Fast Response Positive Adjustable Regulator Features • Guaranted Output Voltage Accuracy within 2% • Fast Transient Response • Guaranteed Dropout Voltage at Multiple Currrents • Load Regulation : 0.1% Typ. • Line Regulation : 0.03% Typ. • Low Dropout Voltage : 1.1V Typ. at I =1A • Trimmed Current Limit : 1A Typ. at Tj=125℃ • On-Chip Thermal Limiting : 150℃ Typ. • Adjustable Output : 1.25~7.75V • Standard 3-pin TO-252 , SOT-223 Power Packages General Description The AT1117 is a low dropout three-terminal adjustable regulators with 1A output current capability. In order to obtain lower dropout voltage and faster transient response, which is critical for low voltage applications, the AT1117 has been optimized. The device is available in an adjustable version and fixed output voltages of 1.8V, 2.5V, 2.85V, 3.3V and 5V, the output available voltage range is from 1.25~7.75V with an input supply below 9V. Dropout voltage is guaranteed at a maximum of 1.2V at 1A.Current limit is trimmed to ensure specified output current and controlled short-circuit current. On-chip thermal limiting provides protection against any combination of overload that would create excessive junction temperatures. The AT1117 is available in the industry standard 3-pin TO-252 the low profile surface mount SOT-223 power packages which can be used in applications where space is limited. Applications • Active SCSI Terminators • Low Volt.
