LM317MABTG:
500 mA Adjustable Output,Positive Voltage Regulator
The LM317M is an adjustable three-terminal positive voltage
regulator capable of supplying in excess of 500 mA 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.
The LM317M serves a wide variety of applications including local,
on-card regulation. This device also makes an especially simple
adjustable switching regulator, a programmable output regulator, or by
connecting a fixed resistor between the adjustment and output, the
LM317M can be used as a precision current regulator.
