Hi,
I have a sensitive analog/RF circuit (1.2V supply, draws max. current 300mA) and for testing purposes I need an adjustable 1.2V (+- ~100mV) supply voltage.
I would prefer on-board voltage regulation, but I cannot find any adjustable linear regulator configuration that could produce such a small output voltage and I don't dare to use switching converters (due to noise issues, right?). There's no on-chip voltage regulation, just some bypass capacitor.
What I'm left with is to take raw DC-supply connection to the chip? If so, do I need to consider some kind of on-board LC-filtering, or just place some bypass capacitors (both close to the chip and power connector)?
I'd appreciate any help with this..
