  • RE: TPS7A84A: Paralleling Multiple TPS7A84A Devices with adjustable operation(R divider)

    Hi Justin, Please ask if you have any questions on this topic at all. If you would like me to help design your parallel LDOs, I can do that if you provide me with your system requirements: Shown below is a representative schematic to parallel the TPS7A84A…

  • RE: TPS7A94: Paralleling for Higher Output Current and Lower Noise

    Hi Justin, Yes, chip resistors are fine. I usually start at 0805 or 0603. Depending on your ambient temperature and the power dissipation, you may be able to select an 0402. You need to review the derating curve in the resistor datasheet to verify you…

  • BQ76952: Parallel output of LDOs to sum up the output current capacity

    Resolved
    Part Number: BQ76952 Hi Team, I am currently designing a BMS including the new BQ76952 chip. For external communication I am using a RS485-Transceiver with current consumption of approx. 50 mA. Additionally I need to supply a SAMD10 with approx. single…

  • RE: TPS7A52: Bias voltage

    Hi Wiebren, There are new papers on parallel LDOs that I wanted to share with you: A Scaleable, High-Current, Low-Noise Parallel LDO Reference Design Comprehensive Analysis and Universal Equations for Parallel LDO's Using Ballast Resistors Parallel…

  • RE: TPS7A85: Serial vs Parallel Design for high reliability

    Hi Antonio, We would recommend the TPS7A85A over the TPS7A85. What is the maximum AC ripple voltage on Vin? We have brand new white papers and an easy to use calculator that shows how to parallel LDOs using ballast resistors (see below). The calculator…

  • RE: 2A or 3A negative output LDO

    Hey Given, Right now we do not have any plans for such a high current negative LDO. However, you could put multiple LDOs in parallel to achieve this. We have released several new design resources for paralleling LDOs to achieve higher currents. A Scaleable…

  • RE: TPS7A57: Simulation error after 1.2V output.

    Hi Mohsin, These are the same settings I have on my end. Have you tried running a single device by itself? Edgar Acosta1 said: May I ask what is the intention? Are you trying to parallel the LDOs? Or what is the purpose of tying the SNS of one LDO to…

  • LM1085: Parallel LDO design possible?

    Resolved
    Part Number: LM1085 Other Parts Discussed in Thread: TPS7A47 Hello, I'm trying to convert 20V/5A SMPS power to 18~19V for my noise sensitive application. I couldn't find a good buck converter for my design. I came across High-Current Low-Noise…

  • RE: SIMO dc-dc converter

    Hi Satyajit, At 5V, 5A I would recommend our highest performance and new LDO, TPS7A57. At 5V, 8A I would recommend 2 parallel TPS7A57 LDO's.The TPS7A57 recommended Vin max is 6V (abs max is 6.5V) but you only need 300 mV extra headroom for performance…
