Part Number: TL783

Tool/software:

Dear TI Support Team,

I would like to inquire about the quiescent current of the TL783. Could you please provide the typical and maximum quiescent current values for this device? Additionally, any related documentation or application notes would be greatly appreciated.

Thank you for your support, and I look forward to your response.

Best regards,

    Hey Tom,


    For linear regulators like TL783, these are being referred as floating regulators, where the voltage regulator regulates the voltage difference between the VOUT and ADJ pin equal to 1.2V. 

    Due to this kind of configurations, the load from ADJ pin instead of flowing into Gnd, flows into the load circuit connected on the LDO output. As the quiescent current is considered as the current flowing into GND and being wasted, in TL783, current IADJ flows into connected load only. Here is the example circuit:

    Here R1 and R2 are being used to regulated the LDO output. The current ADJ will flow into the IL only. 

    Regards,
