Part Number: LP38798 Tool/software: When the output current of the LP38798 reaches the short-circuit current limit (ISC, 0.85 to 1.6A), does the regulator maintain the output at that current level, or does it enter a cycle of turning on and off?
Part Number: LP38798 Tool/software: An SBD is placed at the input to protect the LP38798 from reverse current.
When the input power is OFF, a reverse current of about 1 μA flows, but is there a risk of damage? Also, up to how many A of reverse current…

Hi,
My customer is trying to figure out a few different questions to see if this device will be suitable for their application
1) Is it possible to estimate what the dropout would be for 12V output? Figures…
Part Number: LP38798 Tool/software: I am looking for an LDO to regulate 12V from a switching power to 9V for an microphone preamp circuit.
Is LP38798 a good choice for this?
See thread below regarding microphone preamp:

Part Number: LP38798 Hi Team,
From the LP38798 datasheet, it's mentioned typical value VIL (Typ) = 011V (Datasheet Page Number 6), But we need the maximum value of VIL (Max) =? for Noise margin calculation. Can you please provide the VIL (Max) =?

Part Number: LP38798 Hi
I download the Ultra Librarian based data file to generate Cadence OrCAD 16.6 footprint. but it looks the file doesn't work properly. wihle double click the 2020-06-23_07-09-36.bat file, the Allegro can be called , but it will…
Hi Sada,
Thanks for using Webench. You are correct. The feedback resistor suggestion here is incorrect and will result in 5.6V vout (according to eqns 7 & 8 from datasheet). For now please use table1 (page 16) from datasheet to design feedback resistors…
Part Number: LP38798 Hi Team,
I wonder if CP pin capacitor is mandatory. I checked it's pass FET is PMOS. Does this device still need a charge pump for its basic operation?
The CAP pad is damaged in my board so I wonder if I can open CP pin without…
Part Number: LP38798 Hello Team,
Could you please help to answer the comments and questions below:
I have a new RF amp design where I would like to use the LP38798. Per the datasheet, I noticed that the part uses a charge pump at ~3.5MHz. LDOs with…
