[ 1.5 A Adjustable Output ] Positive Voltage Regulator
Description
The SN317 is an adjustable 3-terminal positive voltage regulator
capable of supplying in excess of 1.5 A over an output voltage range of 1.2
V to 37 V. This voltage regulator is exceptionally easy to use and requires
only two external resistors to set the output voltage. Further, it employs
internal current limiting, thermal shutdown and safe area compensation,
making it essentially blow-out proof.
This device can also be used to make a programmable output regulator, or
by connecting a fixed resistor between the adjustment and output, the
SN317 can be used as a precision current regulator.
Application
◈ Consumer and personal electronics
◈ SMPS post-regulator / dc-to-dc modules
◈ High-efficiency linear power supplies
◈ LED Light Constant Current Controllers
