I'm designing a variable power source from 5V to 30V with 600mA. Input voltage is VIN = 36V. I tried the below circuit.
VREF is given from microcontroller DAC.
I tried using N-MOSFET, P-MOSFET, NPN, PNP (with modifications). I set a the output voltage as 20V. This circuit works fine with no...
Hi There!
I am, for several reasons about building a adjustable LDO. Some of the specifications are:
- min input voltage 4.4V
- max output voltage 3.6V
- 500mV dropout, due to sense resistor
- wide current output range
- at least 20kHz bandwidth @ 10uA load, ideally 100kHz
Pass element shall...
