Part Number: LMZ21700 Hi Support,
I have a question regarding LMZ21700's load regulation at light load.
As illustrated in the plot, <10mA, the regulator seems to enter another operating region. From my estimation (I am using 12V to 5V), the PSM…
Part Number: LMZ21700 Other Parts Discussed in Thread: TPS82150 We are designing new DCDC. now we are considering LMZ21700 or TPS82150 for new design. Both meet our design requirement. we only need 0.2A for 5Vout
from TIonine store TPS82150 is slightly…
Part Number: LMZ21700 Dear Friends-
We are attempting to use the LMZ21700 in our application to charge a super cap. We believe the super cap is being charged effectively using the LMZ21700. When prime power is removed from the application circuit, it…
Part Number: LMZ21700 Hi,
We're designing a product with LMZ21700 . For EMI tests, we shielded the power block with RF shield. Before the power block, we have LC filter, which is BNX026H01L . Should we also use shield for our LC filter for EMI tests…
Part Number: LMZ21700 Hello,
I am using the LMZ21700 with an output at 6V/50mA.
In these conditions, what is the minimum input voltage to ensure proper operations?
Looking to figure 8 and 9 in the datasheet (doc number SNVS872C) does not help, because…
Part Number: LMZ21700 Other Parts Discussed in Thread: LMZ21701 Hello,
Is there a 3D model, preferably a .step for the LMZ21700?
Kind regards,

Part Number: LMZ21700 Hi.
I'd like to get VOUT = 4.5 V (Output Current = 0.1 A) at Vin = 4.75 V using the LMZ 21700, Is there a problem with the dropout characteristic of this device? I saw the figure 8. Dropout of the data sheet (SNVS 872 C) and it…
Hi Romain,
Sorry for the late reply. This is definitely engineering samples that predate the existing finalized LMZ21700 package. Just wanted to be clear that this was never released as an option for during production. This molded package was most likely…
Part Number: LMZ21700 I have observed a failure mode on the LMZ21700SILR regulator, the symptom is as follows:
When the regulator is not powered, the impedance between pin 4 and ground is 4.7 ohms.
When the regulator is powered with 12V, the output…
Part Number: LMZ21700 Other Parts Discussed in Thread: TPS82150 Hi,
Paragraph 10.1.2 (page 27) in the LMZ21700's data sheet says "Use a thin and short trace from the Vout terminal of the output capacitor to the VOS pin." Both layout examples…
