Hi,
I'm trying to power a microcontroller (MSP430G2553) which requires ~1.8V and less than 300uA.
However, my power supply (which is non-negotiable) supplies a variable amount of voltage depending on the load. If a 3.3kOhm resistor is put across it, it provides 1.68V. 1kOhm: 880mV and 10kOhm: 2.16V, etc
I am wondering if there is a simple and easy way to convert some of my current to voltage since I need a higher voltage but can get away with a lower current. I'd really prefer not to use any additional components besides the basics...(like the 78xx)
Thanks so much!
