Hi all, I am using this ADM7172 to gain a 5V output. I want to control its' EN pin with a STM32 GPIO in OD(open drain) mode with a resistor pulling up to 5V, so it's like 0V/5V logic

But, here in the datasheet 

I don't understand what is EN INPUT…

Hello!

I need to power five VCO chips，which input voltage is 3.3V and input current is 200mA. I want to use ADM7172ACPZ-3.3-R7 to power that, and the output current of ADM7172 is 2A.

Because of the VCO is Temperature-sensitive, in order to reduce the…

Hello All,

I am designing the ADM7172 into my system. I have a few questions about the Enable pin.

1) The EN pin appears to need a step input. Do I need to put a diode etc in order to create this step event or can I just use the setup I use in the…

Hi All,

I have a number of ADM7172's being cascaded one after another. I am using them to step down from 6V to 1.8V.

Before you ask, in my application I cannot use switch mode power supplies.

What I am worried about is whether the ADM7172 has…

Due to badly planned power sequencing the outputs (VOUT and SENSE) of an ADM7172 (fixed 3.3V) go down to -1V before the positive power supply (3.7V) is applied to its inputs (VIN and EN). I think the chips that should be powered with 3.3V are now "powered…

Is the soft start cap used to bypass the reference?

Is there a max SS cap I can use?

The description says also that SS needs to be left open when not used, but could the SS pin be used also as a REF in or Track function to lower the output voltage?…

Need 3A for a very low noise RF amplifier.  The ADM7172 would be perfect if it had greater output current.

• Can I parallel the outputs of 2x ADM7172 via small (i.e. 10 mOhm) resistors?
  • If so, what size resistors are recommended?
  • How will…

The data sheets for the ADM7170, ADM7171 and the ADM7172 all list the same thermal resistances even though their rated currents are 0.5A, 1.0A and 2.0 respectively. How can this be so if their maximum junction temperatures are all the same?

线性稳压器ADM7172可否降两个并联使用实现扩流，ADM7172在电流增加的同时，其输出电压会下降，所以我想说能否使用两个ADM7172直接并联在实现扩流并保持输出在电流增加后的稳定性。
