• RE: Double LDO with ADP5134

    Hi Moto,

    I meant that instability might also occur due to other events, such as line and load steps, recovery from output short, etc.

    About the adp223, here's a discussion on paralleling the outputs, and it's also not advisable to tie the two outputs…

  • RE: AD9706 OTCM pin powered from ADP223 LDO

    Larry,

    Thank you for the reply. Attached is the schematic page showing the AD9706 DACs and the ADP223 configured to give +0.5V on each output.

    I was thinking of also connecting the ADP223 so we have a parallel configuration on the outputs so we have…

  • spice model for ADP223?

    Please, pretty please....

    Thank you in advance!

  • RE: Please let me know about ADP223.

    If you parallel the two sections of the ADP223, they will not necessarily share the load equally.  In the worst case scenario, on LDO will be on the verge of overcurrent before the other LDO starts to carry current.  This will result in poor PSRR and noise…

  • RE: ADP323 - Fall back connection

    Meir,

    I am not sure I understand you exact use case, are you interested in using 2 channels of the same ADP323 or 2 separate ADP323.

    Using 2 channels on the same IC and parallel them, although not ideal, can be done. In fact we used to recommend that…

  • AD9706 OTCM pin powered from ADP223 LDO

    We have a development card using 2 x AD9706 DACs to drive a zero-IF IQ modulator that requires a DC bias of 1.15V. We have set the full scale current to 5mA (Radj = 6.45K). We have set the OTCM to 0.5V, derived from a ADP223 Dual LDO. We have a load resistance…

  • ADP223ACPZ output voltage adjustment

    I am using a ADP223 device on one of my prototype cards and I have a question about setting the output voltage on both VOUT1 and VOUT2.

    With VIN at +3.3V I want to have +0.5V on VOUT1 and VOUT2, do I have just a 0R resistor connected between the ADJ…

  • Voltage Regulator for 16-bit ADC AD7626

    We are looking for an appropriate low-noise, low-drop voltage regulator to
    power the 16-bit ADC AD7626. Which device is a better fit : ADP3334 (5V, 2.5V)
    or ADP7104 (5V, 2.5V)? Is there any other voltage regulator that is more
    suitable…
