Part Number: TPS7B4253-Q1 Hi,
I am looking for voltage tracking LDO with smallest package to track down to 1.5V. Device supply voltage is 5V and output current will be under 150mA.
TPS7B4253 should be fine, but I prefer smaller SO8 package and unfortunately…
Part Number: LP38691-ADJ Other Parts Discussed in Thread: TLV767 , LMG1020 , TPS7A90 I would like to use LP3869x- ADJ for Vout =5V.
The load transient waveform that is being provided in datasheet is for Vout = 1.25 V, I would be thankful if you could provide…
Hi Richard,
Could you please send a clearer schematic which shows the circuit to the right of C16? What is connected to Vout (24V)? The snip you sent is very small and blurry.
I have a few steps which will help us debug the circuit:
First DNP Q1-B so…
Hi Tasneem,
How about using a tracking LDO, something like https://www.ti.com/product/TPS7B4255-Q1 , with a resistor + cap divider from VIN -> ADJ/EN -> GND?
It won't be a linear delay, but using a 20k resistor + 0.1uF cap for example should give…
Part Number: TPS7B4254-Q1 Hello E2E team,
Referring to section 6.1, footnote 4 specs of the device datasheet, "When the (ADJ – IN) voltage is higher than 18 V, the (ADJ – OUT) voltage should be maintained lower than 18 V, otherwise the device can be damaged…
Hi Lilian,
In all LDOs with a feedback network of resistor dividers, there is a contribution to VOUT from the FB/ADJ pin current. However, for the TPS7B84-Q1, to ignore the FB pin current error term in the VOUT equation, set the feedback divider current…
Part Number: LP38691-ADJ Other Parts Discussed in Thread: LP38691 , Hello,
I've see your answer to previous similar question, but I was too busy to answer you..
Neitheless I found differents working of the same component on the same board !!!
On the…
Part Number: LP38691-ADJ Hello,
I have a serious problem with limitation current of the device.
On an actual PCB we use LP39681-adj LDO regulators, and I have problem with them...
Current limiting doesn't work anyway, if I short output or if I connect…
Part Number: LM4041-N-Q1 Other Parts Discussed in Thread: LM4041-N Tool/software: I'm trying to build a current source circuit (for small currents in 5uA range) and I found that I can use lm4041 adj with 2 pnp transistors to build it. (2n2905 & 2n3964…
Part Number: LM2596 Other Parts Discussed in Thread: TPS7B88-Q1 Tool/software: Hi team,
I have two questions about LM2596T-ADJ/NOPB
Q1. Is the thermal resistance between the junction cases correct to be calculated using the thermal resistance of "R θ JC…
