HMC8410 supply

In the datasheet to the product, the following order of power-up is indicated:

1. Connect to GND.

2. Set VGG1 to −2 V.

3. Set VDD to +5 V.

4. Increase VGG1 to achieve a typical supply current (IDQ) = 65 mA.

5. Apply the RF signal.

 

What are the consequences of power-up in that order.

 

1. Connect to GND.

2. Set VGG1 to −2 V.

4. Set VDD to +5 V.

5. Apply the RF signal.

 

How can I implement the correct order of power-up? (I can not find the right components for this.)
Enough to use linear regulators with have the pin "enable" and "power good"?

 

TY
