  • TPS7A8300: PSRR issue

    Part Number: TPS7A8300 I'm reading this article Understanding power supply ripple rejection in linear regulators PSRR=20log(Ripple input/Ripple output)=20log(Av/Avo) But why Ripple input/Ripple output=Av/Avo, I don't understand that.

    Part Number: TPS7A8300 Hi, I would like to know whether the designs given below can be used in the LDO ( TPS7A8300RGRR) to produce the desired output voltages. Features:- 1. Input Voltage = 6.3V 2. Output Voltage = 5V 3. Maximum Current = 1.5A Features…

  • TPS7A8300: TPS7A8300

    Part Number: TPS7A8300 Hello there, Sorry, the part number was wrong in my email eariler. I have a question again. I have a question about TPS7A8300. We have to perform the pretest to DVM(digital multi-meter) before SMT work to check the LDO is okay…

  • TPS7A8300: start up issue with feedforward capacitor

    TI Thinks Resolved
    Part Number: TPS7A8300 I'm reading this artice Pros and Cons of Using a Feedforward Capacitor with a Low-Dropout Regulator (ti.com) in part 2.1 Start-Up Issue It's assumed that with Cff, VOUT tracks VFB during tref time. Which means that VOUT=VFB…

  • TPS7A8300: TPS7A8300 Design Questions

    Part Number: TPS7A8300 Hi, Tps7a8300 outputs 2.5v/2a, and 20ns ringing occurs during load 0a-0.3a. What are the reasons? Loop or PCB? In the tps7a8300 specification, does CFF have to use 10nf? What will be the impact of removal?

  • TPS7A8300: questions of TPS7A8300

    TI Thinks Resolved
    Part Number: TPS7A8300 Dear team, From the specifications of TPS7A8300ARGWR and TPS7A8300RGRR, it can be seen that the packages of these two materials are the same. Can these two materials be replaced? Many Thanks, Jimmy

    Hi Vikas, Sounds good. I will wait for that. Regards, Nick

  • TPS7A8300: TPS7A8300

    Part Number: TPS7A8300 Hello Team, I am using TPS7A8300RGRR in one of my project for 5V to 3V3 Conversion. In that, the Power Good (PG) Pin is always in Low state (i.e 0V) even the VIN, EN & VOUT are within the range (i.e Both I/P & O/P Voltages are fine…

  • TPS7A8300: cons of using feedforward cap

    TI Thinks Resolved
    Part Number: TPS7A8300 Hi, I'm reading SBVA042. In section 2.1 Start-Up Issue. The start-up time is divided into tref and tcff. At t1 , the PG pin is asserted (pulled up to VOUT) when VFB reaches the reference voltage because the internal power-good…

  • TPS7A8300: sample test fault

    Part Number: TPS7A8300 Hi Ti engineer， Use TPS7A8300RGRR r eplace SGM2049XTRL20G/TR,But TPS7A8300RGRR did not output in specific tests. Input 5.5V output 5V, start current 3A, duration 1.2ms, normal current 780mA, this power supply to the AD chip and operational…
