LM317D2TG Linear Regulators (LDO) by ON Semiconductor

Linear Voltage Regulator, 1.5 A, High PSRR, Adjustable, Positive

The LM317 Low Dropout (LDO) Linear Voltage Regulator is an adjustable 3-terminal positive LDO 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. The LM317 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 LM317 can be used as a precision current regulator.
