I'm using ADL5611 powered by dropping resistor, the power is 8 Vdc and dropping resistor is 32 Ohm, to obtain 5Vdc at pin 3 of ADL5611 at 94mA of absorption. The ADL5611 device does not start well. To pin 3 (RF out) the voltage is 3.1 Vdc and the device absorbing 153mA, and remains in this state. The voltage of 8Vdc is generated by a linear voltage regulator that limits output start-up current at 1 A. The ADL5611 how much current is required to turn on properly?
This inrush current should be included in the datasheet. We manage to take some data during the initial power on and the voltage ramp is using a 5V regulator circuitry. During power on, at around 3.5V, there is a threshold behavior and it's clearly seen in the kink. The horizontal axis is in seconds. Meanwhile, the regulator current is monitored to show a spike of 600mA. This inrush current will render some LT(basically ADI) regulators useless.
