Two ceramic multilayer capacitors of minimum 100 nF with low Equivalent Series Resistance (ESR) should be used in order to meet
these specifications.
Output voltage towards the card, including ripple.
I/O
I/OUCn pin has an internal 11 k pull-up resistor to V
Maximum value measurement based on a 125 mA (sum of all card supply currents on pins V
converter and inductance efficiency; depends on PCB layout and external component quality (inductor, capacitor).
