Consult to be a 0-5V digital power supply

Want to use a linear device, such as LDO to be a 0-5V (or 2-5V) digital power supply. The voltage output is regulated by the microcontroller DA output. Digital power supply power should not exceed 0.3W. With the allowable adjustment, the chip size is as small as possible. Want to consult with the kind of chip and circuit. Thank you.

    Hi ,

    Unfortunately we do not have an currently LDO that can regulate an output voltage down to 0 V. To regulate from 2-5 V you can use an adjustable LDO that is rated for the output current that your load required.

    Very Respectfully,
    Ryan
