Part Number: TLV61220

Hi,

I am looking for procedure for testing Quiescent current as mentioned in datasheet.

Quiescent current Vin : i will set Iout =0mA,VEn=Vin=1.2 ,Vout=3.3V(configured using feedback resistors) and i will measure the input current.Please let me know this procedure is correct else,please guide me.

Quiescent current Vout: i will set Iout =0mA,VEn=Vin=1.2 ,Vout=3.3V(configured using feedback resistors) and i will measure the output current . since Iout is set as 0mA, no current will be expected at output. Then what is this quiescent current means? please guide me.

Regards

Shankar

Hi Shankar
Iq fundamentally comes from two inputs: VIn and Vout. so there are two spec.
You could add a power supply in Vin and another one in Vout to test the Vin current and Vout current.
Another thing, you need to guarantee no SW.
You can take this paper as a reference.

So i understood that Iq fundamentally comes from two inputs: VIn and Vout from the shared documents.

The Iq specification for Vin should be measure at input pin and Iq specification for Vout should be measured at output pin. Can you confirm this.
