My son is doing some pixel controls for his science project at school and I am trying to get the BOM ordered from Mouser. There were three parts that were discontinued but I believe I have suitable replacements for those. There is one part on backorder and its the 926-2950CZ-5.0/NOPB - LDO Voltage Regulators 5.0/100Ma Low Pwr LDO

The new one I found is 926-LP2950CZ50LFT3 - LDO Voltage Regulators Series of Adjustable Micropower Voltage

The only difference I noticed was the "Adjustable" part. Can I use this instead? I know nothing of this and could really use some guidance. I don't have time to wait for a backorder.

Any input is greatly appreciated, thanks.
