TPS7A4201: Enable Pin Input Impedance

Keith Keller

Part Number: TPS7A4201

Hello,

Could you please let us know if there is any resistance internally on the enable input EN pin on the TPS7A4201?

In the block diagram in section 7.2 does not show anything.

We are using a different LDO which has an open-drain configuration which does not work for us.

Thank you, Keith

    Hi Keith,

    TPS7A4201 does not have a dedicated pullup or pulldown; therefore, it is intended to be driven at all times to either logic high or logic low. If your application does not require Vout to be enabled separately from Vin, you could tie EN to Vin.

    Very Respectfully,
    Ryan
