LM317 Voltage Regulator
Texas Instruments' 3-terminal, 1.5 A, adjustable positive-voltage regulator
Texas Instruments' LM317 device is an adjustable three-terminal positive-voltage regulator capable of supplying more than 1.5 A over an output-voltage range of 1.25 V to 37 V. It requires only two external resistors to set the output-voltage. The device features a typical line regulation of 0.01% and typical load regulation of 0.1%. It includes current limiting, thermal overload protection, and safe operating area protection. Overload protection remains functional even if the adjust terminal is disconnected.
Features
- Output-voltage range adjustable: from 1.25 V to 37 V
- Output current greater than 1.5 A
- Internal short-circuit current limiting
- Thermal overload protection
- Output safe-area compensation
Applications
- ATCA solutions
- DLP: 3D biometrics, hyperspectral imaging, optical networking, and spectroscopy
- DVR and DVS
- Desktop PC, digital signage and still camera
- Energy harvesting
