  • TPS7A8300: TPS7A8300 EN deglitch filter

    Resolved
    Part Number: TPS7A8300 Hi TI experts, In our design, there is an uncontrollable high pulse (3.3V) applied to EN pin before normal power up sequence starts. The pulse width is about ~10ns. Is there any deglitch filter inside TPS7A8300 EN pin which can filter…

  • TPS7A8300: Startup issue with TPS7A8300RGRR

    Part Number: TPS7A8300 Hi TI experts, For the design of TPS7A8300RGRR, we use external resistors to set output voltage. The design parameters are as follows, Vbias=5V, Vin=1.2V, Vout=0.9V,and using an external power supply to control the EN of TPS7A…

  • TPS7A8300: EN threshold

    TI Thinks Resolved
    Part Number: TPS7A8300 Hi TI experts, How to understand the EN threshold from datasheet? Given EN sweeps from 0<->3.3V: 1. From 0V-3.3V: once EN rises above 1.1V, the LDO turns on, right? 2. From 3.3V->0V: When will LDO be turned off? Below 1.1V…

  • TPS7A8300: TPS7A8300 output bumped up

    Part Number: TPS7A8300 Hi TI experts, I used TPS7a8300 in my design to generate A1.8V from A2.5V. There is another power rail P3V3_Z0 which was enabled ~550ms later than A1.8V. Observed once P3V3_Z0 is enabled (ramped up), A1.8V is bumped up from 1.8V…
