• 1.Q:Why is my LDO not regulating properly?

    A:Many reasons possible: current limit has been activated, thermal shutdown has been exceeded, dropout voltage spec not obeyed,
    ESR of caps rules not obeyed, etc.

    2.Q:How may I obtain the reference voltage out of an adjustable LDO?

    A:Hook the ADJ pin directly to Vout.

    3.Q:What is the accuracy of my LDO?

    A:The accuracy of the LDO is the VREF (ADJ) voltage accuracy. It is typically 1% at certain conditions. If a resistor divider is used for an
    ADJ device, the total accuracy will be affected by the external resistance tolerance.
