TO-252-3L
SN317Mx
[ 0.5 A Adjustable Output ] Positive Voltage Regulator
Description
The SN317 is an adjustable 3-terminal positive voltage regulator
capable of supplying in excess of 0.5A 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.

* Load and line regulation are specified at constant temperature. Change in VO due to heating effects
must be taken into account separately. Pulse testing with low duty cycle is used.
