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…
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…
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 Are there any known issues with this device? I have experienced a failure in a new design after about 20 hours of normal operation. The device steps 12V down to 5.2V. The output impedance to ground now measures about 1.4ohms and…
Part Number: LMZ21700 The front page of the data sheet says that it is OK for startup into pre-biased outputs, but there is no information in the datasheet concerning any functional details or constraints.
Is the following an accurate description of the…
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…
Part Number: LMZ21700 Hello,
We use this IC in an automotive application to convert a +12V battery rail to 1.8V and have observed a failure. The output impedance between pin 4 and ground is 4 ohms and the output voltage is zero. Are you aware of any conditions…
Part Number: LMZ21700 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models I would need an AC model for the LMZ21700 in order to check the total impedance of the power delivery network in a digital system.
My concerns are the…
