REG1117-3.3/2K5

The REG1117-3.3/2K5 is an 800mA dropout positive regulator in 4 pin SOT-223 package. This three-terminal 3.3V voltage regulator is easy-to-use. The low dropout voltage allows its use with as little as 1V input-output voltage differential. Laser trimming assures excellent output voltage accuracy without adjustment An NPN output stage allows output stage drive to contribute to the load current for maximum efficiency. It is used in SCSI-2 active termination, hand held data collection devices, high efficiency linear regulators, battery powered instrumentation, battery management circuits for notebook and palmtop PCs, Core voltage supply like FPGA, PLD, DSP and CPU.

• 2.85V model for SCSI-2 active termination
• Output tolerance of ±1%
• Dropout voltage of 1.2V(max) at IO = 800mA
• Internal current limit
• Thermal overload protection
