TLV773: Quiescent current.

Kengo.Y

Part Number: TLV773

Tool/software:

Hi team,

Ground current is constant even if output current increases as shown below.
Why is this?
I believe that as output current increases, Ground current also increases.
And, what different between Ground current and Quiescent current?

Hi Kengo,

Please see page 3 of Understanding the Terms and Definitions of LDO Voltage Regulators to learn more about quiescent current, otherwise known as ground current.

As well as see page 11 of LDO Basics (Rev. A) (ti.com) to learn more about quiescent current.

These resources should answer your questions!

Please let me know if you have additional questions.

Best,

Hannah

Hi Hannah,

Thank you for reply.
I understood.

By the way, I can not see LDO Basics.
Could you check it?

Hi Kengo,

Please try this: LDO Basics (Rev. A) (ti.com)

You can also look up LDO basics in your internet browser and it should pop up.

Hi Kengo,

Please look up LDO basics on an internet browser. This should work. Additionally, we have videos available to cover LDO basics, which you can also find on the web.
