The Texas Instruments REG1117/2K5 is a versatile linear voltage regulator designed for a wide range of applications. It offers an adjustable output voltage with a maximum current capability of 800mA. The device accepts an input voltage ranging from 3.7V to 15V and provides a regulated output with a typical accuracy of 2% and a dropout voltage of 1100mV at 800mA.
Key electrical characteristics include a typical quiescent current of 4mA and a PSRR of 29dB at 100 KHz. The regulator is protected against overcurrent and overtemperature conditions, enhancing its reliability in demanding environments. It requires a minimum load capacitance of 10µF for stable operation.
Packaged in a surface-mount SOT-223-4 or TO-263 package, the REG1117/2K5 is suitable for space-constrained designs. Its operating temperature range is -40°C to 125°C, making it appropriate for industrial and commercial applications. The adjustable output feature makes it adaptable for various voltage requirements, including SCSI-2 active termination.
Applications for the REG1117/2K5 include battery-powered instrumentation, battery management circuits for portable devices, and core voltage supplies for FPGAs, PLDs, DSPs, and CPUs. Its high efficiency as a linear regulator also makes it suitable for power management in notebooks and palmtops.
