Overview
The NCV317BTG is an adjustable 3-terminal positive Low Dropout (LDO) linear voltage regulator produced by onsemi. This regulator is capable of supplying an output current in excess of 1.5 A over an output voltage range of 1.2 V to 37 V. It is exceptionally easy to use, requiring only two external resistors to set the output voltage. The NCV317BTG is designed with internal current limiting, thermal shutdown, and safe area compensation, making it essentially blow-out proof. This device is suitable for a wide variety of applications, including local, on-card regulation, and can be used to make programmable output regulators or precision current regulators.
