LM317MADTRKG

ON SEMICONDUCTOR  LM317MADTRKG  芯片, 线性稳压器, 0.5A, 1.2-37V, TO-252-3

The is an adjustable 3-terminal output Positive Voltage Regulator capable of supplying in excess of 500mA over an output voltage range of 1.2 to 37V. 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 regulator serves a wide variety of applications including local, on card regulation. This device can also be used to make a programmable output regulator or by connecting a fixed resistor between the adjustment and output, the regulator can be used as a precision current regulator.
