TPS7A85 dynamic Vout change by the GPIO

Other Parts Discussed in Thread: TPS7A85

Hello,

Can I change the vout of TPS7A85 dynamically by changing the ANY-OUT voltage setting pins?

Best Regards,

    Hi Ryuji,

    Yes you can dynamically change the output voltage by changing the ANY-OUT pins settings. You should be aware that when setting the output lower, since LDOs do not sink current, the output voltage will be held high by the output capacitor until discharged by your load. Also if you set the output voltage higher than the input voltage, the LDO will go into dropout.

    Best regards,
