Part Number: TPS799-Q1 Tool/software: Hello,
I have downloaded the PSpice average model for the TPS799-Q1 (part number TPS79918QDDCRQ1) from the TI product page. However, the .LIB file contains $CDNENCSTART encryption blocks, and my simulation tool…
Part Number: TPS799-Q1 We need to know VRM Equivalent inductance for TPS79901QDRVRQ1 to set low frequency limit for Decoupling analysis to ensure power integrity. Please provide the VRM Equivalent inductance for TPS79901QDRVRQ1 as soon as possible.
Part Number: TPS799-Q1 I would like to confirm the cause of the unexpected output in EN low for TPS799-Q1.
I attached the waveform.
The conditon is VIN = 3.3V, EN = 2.7V, input capacitor 4.7uF and output capacitor 2.2uF.
The output voltage in…
Hi Randy,
What size capacitor are you planning to use?
TPS799-Q1 was optimized for an output capacitor of 2.2uF. As such, this particular LDO was tested and characterized with 2.2uF. While larger output capacitors are okay, it is important to keep…
Hi Charlie,
Thank you for reaching out.
Can you share your schematics?
This is a known problem for TPS799, and i t seems like this issue is related to the Vin rise time and/or load.

Part Number: TPS799 Other Parts Discussed in Thread: TPS7B81-Q1 Hello all,
In my design, I'm using the TPS79933 LDO
I was looking for the output rise time in order to make there is no significant inrush current at startup.
I came across this graph…
Part Number: TPS799 Hi,
My customer is using TPS79901. He has issue big inrush current at start-up. Peak current value is about 2.57A. He has questions below.
Q1: What is "Inrush Current Protection with EN Toggle" in datasheet ? Could you let me know…
Hello,
You are thinking of switching converters. The TLV733P-Q1 is a linear regulator. Linear regulators do not have switching frequencies or minimum on time. Please see this white paper for further details on the fundamentals of linear regulators.…
