  • LM317: Review of the LM317 circuit construction.

    Part Number: LM317 Hello team, I want to get feedback on the circuit I designed. First of all, the Spec. is as follows. 1. Input voltage: 9 to 24V 2. Output voltage: 2 to 5 V 3. Output current: 200 to 700 mA In the attached circuit 1. Input capacitor (Cin)…

  • LM317: Power supply with LM317

    TI Thinks Resolved
    Part Number: LM317 Hi team, There has a question about LM317. If the LM317 shuts off the input and the output is connected to 18V power, is it possible to do this? Thanks.

  • LM317: LM317 Question - Use as an OVP device

    Resolved
    Part Number: LM317 I would like to use the LM317 as a means of temporary overvoltage protection. By this I mean: I would configure the regulator to regulate at 15V, but for most of the time, I would be applying 4-14 volts to it, which would pass through…

  • LM317: Question about a power supply with LM317

    TI Thinks Resolved
    Part Number: LM317 Hi, I have a question about a power supply with LM317: Is there a "Temperature" vs "Expected life" for LM317?, Does the hotter it runs the less expected working life it has? Thanks,

  • LM317: Automatic Voltage Source using LM317 LDO regulator

    Part Number: LM317 Hi, I have a query regarding LM317. I have a microcontroller which produces PWM pulses as output. Can this output be used as a feedback for the LDO LM317? My intention is such that I am going to give this pulse to a MOSFET as gate pulse…

  • LM317-N: Require an unencrypted Spice model for LM317-N

    TI Thinks Resolved
    Part Number: LM317-N Other Parts Discussed in Thread: LM117QML-SP Hello, I discovered that there is no model available for LM117QML-SP, but apparently it is ok to use the LM317-N model, I downloaded a model for this via the Pspice OrCAD tool for TI but…

  • LM317: How will LM317 perform if working in an ambient temperature of -30deg C with no/very light load?

    TI Thinks Resolved
    Part Number: LM317 Hello, LM317 has a recommended operating temperature range between 0 to 125 deg C. If in the situation that the ambient temperature is far below (-30 degC for example) and the LDO has very light load, meaning very minimum self-heating…

  • LM317: LDO Circuit design guide

    TI Thinks Resolved
    Part Number: LM317 Do we have any design guide for below circuit with LM317 solution? Customer want to know the power loss of LM317 and TIP73 and to see whether below circuit is suitable for the demand voltage and current or not? Input Voltage:20V Output…

  • LM317: 220VAC to 0-30V DC LM317 CIRCUIT

    TI Thinks Resolved
    Part Number: LM317 Hello, I want to design a circuit that can take 220V mains voltage and can be adjusted with a potentiometer and outputs 1-27V. For this, I first converted the mains voltage to 24V AC voltage with the help of transformer. Then, I rectified…
