  • Overview
    LM317DCY Product overview

    The LM317DCY is an adjustable three-terminal positive Voltage Regulator, capable of supplying more than 1.5A over an output-voltage range of 1.25 to 37V. It requires only two external resistors to set the output voltage. The device features a typical line regulation of 0.01% and typical load regulation of 0.1%. It includes current limiting, thermal overload protection and safe operating area protection. Overload protection remains functional even if the ADJUST terminal is disconnected.

    LM317DCYRG3 Product overview

    Say goodbye to unstable voltages with this standard LM317DCYRG3 linear regulator from Texas Instruments. This voltage regulation device"s single output can produce a current up to 1.5 A. Using the part will provide the power your application needs by requiring a voltage only of 4.2 V and not exceeding a voltage of 40 V. With an adjustable output that has a voltage of 1.25 to 37 V, this is power management at its best. Using a load regulation of 0.5%Vo and line regulation of 0.04%/V is needed for a programmable DC power supply. Tape and reel packaging will encase the product during shipment, ensuring safe delivery and enabling quick mounting of components. The maximum dropout voltage is 3@1500mA V. This voltage regulation device has an operating temperature range of 0 °C to 125 °C. Its polarity is positive.

    LM317MSTT3G Product overview

    The LM317MSTT3G 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.
