Input voltage range of the REF5045A-Q1
Hello,
I am planning to use REF5045A-Q1 to obtain low drift and precise voltage which will be the control voltage of my oscillator (VCOCXO). I have some questions about its input voltage range. In the product datasheet, under the section of 7.5 input voltage range is given as VIN = (VOUT + 0.2 V) to 18 V.
1. As indicated in the datasheet, when we look "Figure 10. Quiescent Current vs Input Voltage" graph, it is shown that IQ current is not altering (mostly stable at 25 °C) between the voltage range of 5-18V. Does it mean that if I supply 9V to the input pin, Vin (pin 2), will REF5045A-Q1 still yield 4.5V as given in the datasheet?
2. Or Can I supply any voltage in between VIN = (VOUT + 0.2 V) to 18 V?
3. Or is there any nominal input voltage that has to be given as an input voltage (to Pin 2) for REF5045A-Q1 to yield a 4.5 V output?
Thank you in advance,
Huriye ÖZDEMİR.
