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 bination 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 Voltage Logic Supplies
- Battery-Powered Circuitry
- Post Regulator for Switching Power Supply
