  • TLV743P: Application problem

    TI Thinks Resolved
    Part Number: TLV743P Hi Team， Datasheet shown that the TLV743P overtemperature protection is 160℃. But they don't provide the tolerance. Would you please help me to provide it? For this chip, does they will verify the production overtemperature protection…

  • TLV743P: Question about Output Noise Voltage (Vn)

    Part Number: TLV743P Hi team, Customer asked a basic question on Vn in LDO. I understood that the RMS noise is specified over a frequency range. But I wondered what it means in the system. Could you explain what does it do and how it affects in system…

  • TLV743P: LEAKAGE ISSUE urgent

    TI Thinks Resolved
    Part Number: TLV743P Hi team, my customer discover large leakage (1mA) at 3D3V_RTC_AUX Vin of TLV74315 during "coin battery supply", as you can see below the red circle, when they decrease the resistor value, the leakage disappear, also when…

  • TLV743P: TLV743P PSRR measurement tips and condition

    TI Thinks Resolved
    Part Number: TLV743P Hi, I was trying to measure the PSRR of TLV743P with below configuration 1. Cin = Cout = 0402/X5R/1uF/6.3V capacitor 2. Vin = 2.3V, Vout = 1.8V, I-load = 300mA May i know if this is the correct operating condition for the PSRR measurement…

  • TLV743P: TLV743 output voltage not stable

    Part Number: TLV743P Hello, I am using TLV743 for 2.5V fixed output. I have attached schematic for reference. When i am applying EFT (100KHz burst) level 4, at the output 2.5V goes to 1.5V but my input to the IC which is 5V is stable. Output load = 5mA…
