I am using ADP122 3V3 fixed output LDO which outputs 4.2V with no load.
With 1k load the output goes down to 3.8V and with 0.3k back up to 4.3V.
The input voltage is 4.8V and 1uF ceramic caps (with unidentified ESR) are used at the input and output…
you could but you system performances would decrease
ADuM6404 pin 15 (VISO) - you need 5V because ADP122 will use this value to power ADE9000 with 3.3V. This choise is linked to ADUM high noise at VISO pin compared to ADP.
As a direct consequence…
Please explain what is the difference between ADV7612 and ADV7511 power supply requirements?
Why on EVAL-ADV7612-7511 board power supplies for ADV7612 and ADV7511 are also different?
1). Why for ADV7612 1.8V and 3.3V power supplies…
1. Pin C24 should connect to the DVcc supply which is 3.3V.
2. The ADN4605 has four distinct supply pins (actually 5 including ground): VCC, DVCC, VTTI, and VTTO
VCC, VTTI, VTTO can operate on over a nominal range of 2.5V to 3.3V, where DVCC…
